M3!0$!5 [SCRIBEEEE]

!שלום כולם
hahah hey everybody TessaN here! If ya'll didn't know what that means.. its 'hey everybody' in Hebrew. o and to everyone that didn't know I'm Jewish lol I don't randomly know Hebrew don't worry, it's like my second language.
alright so anyways today in class we were a little behind, but it's okay because we still got a lot done! First, we handed in our homework. Then we went over the answers for the quiz about MEIOSIS. After that, we went over the homework. The homework was about crossing traits using punnett squares and explained how the dominant gene is used over the recessive gene. If you have Gg, the offspring are the big G, because the 2nd allele doesn't matter. The genotype are the letters (XX GG gg Ss Yy) and the phenotype are the traits/what it looks like (tall, short, green, yellow) Then, with about 10 minutes left of class we started the face lab! Mrs. Stein was nice enough to let us choose our own partners, and whatever we didn't finish we did for homework.

SCRibo de dayo

Hola, mis amigos!

Sorry ofr the late scribe post. On Monday, we mostly talked about meiosis. Meiosis the making of egg and sperm, and involves many steps, divided in two phases, meiosis 1 and meiosis 2. It mostly occurs in a mitosis like form like this picture:
Most of the stage's names are mostly similar to the mitosis stage names, so try not to get confused!


That's all for today folks! Hasta Luego!

Scribin' it up: Tuesday

Today we had a substitute because Mrs. Stein wasn't here. :( We sat at new seats and took a quiz about Meiosis. After, we went over the quiz. Then we read over UP 21. She gave us a mini reading quiz to go over what we had learned. Once we went over the reading quiz she gave us a handout and we worked on UP 29-31. This is what happened today!

Biology : Meiosis - cell division YAY!!!!!!

-Protein Synthesis Activity- (Nov. 18th, 2011)

Hey guys!! It's Eunice C!

Today, thankfully there was no other homework due besides previewing UP. 15-20. BUT, remember to consistently work on homeworks that's due Monday: Tribune article, UP 39-40, UP 23-28, UP 15-20, read 13.3, and KEEP STUDYING FOR THE DNA/RNA TEST ON TUESDAY!
So today, we did a protein synthesis Activity with our lab group partners! WOOHOO!! We had to construct a model of protein synthesis with nucleic acid model kit. First, we put together a double-stranded DNA molecule with a sequence. IF you got Mrs. Stein's initials, you moved onto the next step. Next, using the left strand DNA molecule, we constructed a complementary mRNA nucleotide strand. (Transcription!) *Remember, to construct mRNA from DNA, the enzyme RNA polymerase is used, with complementary mRNA nucleotide strand, and all of these occur in the nucleus. And uracil is used instead of thymine.
Last but not least comes translation. *Translation occurs in the cytoplasm. We had to attach amino acid to tRNA, then attach it to the codon of mRNA, and attach with hydrogen bonds. And continue this for the next 2 mRNA and amino acid groups.
Finally, if you have 3 initials you are good to go!


YAY its finally posted.....haha this is a video of protein synthesis! ENJOY

PROTEIN SYNTHESIS

hey guys!! its kelly

so we started off todays class by going over last nights homework which was the double bubble map and then we started talking about PROTEIN SYNTHESIS which is the process in which proteins are made

PROTEIN SYNTHESIS has two parts: TRANSCRIPTION and TRANSLATION

TRANSCRIPTION is when DNA is used as a template to make messenger RNA & it takes place in the NUCLEUS

TRANSLATION is when the messenger RNA is used to make PROTEINS in the RIBOSOMES

*Mrs. Stein also said that we should know that DNA is transcribed to RNA & RNA is translated to PROTEINS*

I hope this video helps!!!

DNA Replication

Hey guys! Heidi here.

Okay, so today in class we talked about DNA REPLICATION.

We learned:
-Genes- are a segment of DNA which codes for a protein (traits)
-where DNA replication happens and when it happens
-what each strand stands serves as
-Histones- proteins which DNA is wrapped around

After our wonderful, yet confusing conversation, of DNA REPLICATION we had been given time to do our homework. We also got to have a one on one conversation w/ Mrs. Stein about DNA REPLICATION, because some of us had difficulty understanding the material. So I found a video that I thought MIGHT help.

Lego DNA

Hi everyone its Eleni! Today (Monday) in class we did a lab where we built DNA models using different color lego like pieces. The packet held the instructions to building the rungs and where to put the rods and hydrogen bonds. The cytosine (blue) connected to the guanine (yellow) and the adenine (orange) connected to the thymine (green). It was a nine rung ladder and the nitrogen bases were held together with a white hydrogen bond. The black deoxyribose sugar held together the base and the phosphate. We then took off the left half of the model and rebuilt the right side making a whole nother DNA structure. I did take pictures in class with my phone but as I've mentioned in past posts I am not good with computers so I'm not going to take the risk plugging my phone into the computer! But everyone was in class and hopefully can remember what it looks like! that really all we did in class today so everyone...STUDY!!

Also everyone pleaseeeee request a letter from Mrs. Stein to give the children a christmas present!! Pair up with a friend and help donate!!

Thursdays class

Hey its Mike and on Thursday we talked about DNA. DNA was a very hard topic and was very complex. So i am going to try to explain to you the structure of DNA. DNA is made up of nucleotides joined into long strands or chains by covalent bonds. As you can see on the right diagram DNA has nitrogen bases these are simply bases that contain nitrogen. DNA has four kinds of nitrogen bases these are adenine, guanine,cytosine,thymine. These are joined together by a covalent bond. That is the structure of DNA and it contains our genes and contains instructions to make proteins so it is very important in our lives.

Muddy water (Trent)

My muddiest point is, a virus reverses the process of normal proteins DNA->RNA

virus was RNA->DNA->RNA->

correct?

Scribe...

Yesterday:

In the beginning of class we got stamped for our home work which was page 32, primary and secondary immune response. And also 37-40, HIV Infection and T Cell Counts. Then we had a quiz that was on 35.2 and 35.5 (which we had to read carefully). We also did it with a partner :D. After we were all done with the quiz we took notes and talked about Acquired immunity. Active immunity is when your body produces antibodies. And passive immunity is when antibodies are obtained passively. The last think we did was watch a video about malaria. Malaria is an protist. The vector is the mosquito. And it is transmitted by bites. This can be prevented by i think a bed net which you sleep under which cost five dollars.

Today:

In the beginning of class today we started out with going over the quiz we had yesterday on 35.4 and 35.5. We also did our disease of the day. And today's disease was Lyme disease. The agent of disease is bacteria. It is spread through the black-legged ticks. For the rest of the class we asked questions about the test we have tomorrow.

(it wasnt letting me post any pictures...)

Next scribe is Mike. Hopefully he will remember.

muddy pointttttttttttttttttttttt

i dont get when a virus is destroyed where does it go and what takes it there

Stuck in the Mud

My muddiest point would be the difference between B and T cells. Help!

Why is my point in the mud????

Heyy ya'll so my problem is...... Specific and Non-specific Defenses!!!!!!! yayyyyy Yo class whats the difference????? I'm sooooo confusedddd!!!!!!!! please helppp meee!!!!

Specific & Non-Specific Defenses...Dun...Dun...DUN!

My muddiest point is the overall and general concept of specific and nonspecific defenses! I understand the little, specific, and detailed parts of it but, I just need a brief answer that sums it all up! Thankssyouss.

kind of a random question but at the same time kinda not :)

I HAVE A QUESTION FOR MRS. STEIN. so lets say that someones post doesnt get commented on, do you go and answer all the questions?

DEFINATELY NOT A CLEAN POINT!!

first off id like to appoligize in advance for my horrible spelling!

so anyways...its eleni, and i know a lot of people are already saying this but I DO NOT GET THE DIFERENCE BETWEEN A T-CELL AND A B-CELL and what ever other cells there are!!!!!! please help me :) that chart we did for homework and went over in class was a little iffy for me (conffusing) k thanks byeeee

Muddiest Point

I have trouble with what happens after the macrophage consumes the virus. And how the T cell activates the helper T cells. Help? :(

Muddiest Point

Hey it's Allie. So my muddiest point is really simple, But I'm confused about T cells and B cells. What's the difference and the types?

Muddiest Point

Hey, guys I'm kind of confused on the difference between a regular T-cel and a helper T-cell. Also I'm kind of confused on how T-cells change into helper T-cells.

Muddiest Point!

Hi, My Muddiest Point is kind of simple. I don't understand what te difference between the agents of disease are!

I know the difference between bacteria and viruses, but I don't understand what makes Fungi, and pathogens, and Protists different!

Stuck in the Mud

Muddiest Point

My muddiest point is the process after antigens go into the macrophage, the example Ms. Stein showed in class. I'm kind of confused on what all the different T cells are doing after that.

Muddiest point

Help! My muddiest point is the difference between b cells and t cells. I have trouble understanding what they do. Help me.

Muddiest Point.

My muddiest point for this unit is basically the whole map we did in class. With the specific defenses and non specific defenses. I no some of it, but i don't understand it all.

Question of the Day

HEY!ITS JON, AND MY MUDDIEST POINT IS THE DIFFERENCE BETWEEN ALL THE DIFFERENT KINDS OF T CELLS THERE ARE AND ALL THEIR FUNCTIONS. HELP NEEDED!!!!

HEY YA"LL!!

Hey guyysss!! ERIKA here! Alrighty so my muddiest point is the difference between the B-cells, what they do, and how they help?! Gracias!

this is a muddy section

Hi its Mike my muddiest point is difference between all the t cells and what there differences are please help me

Muddiest pointo

Hi it's catie! So my muddiest point is the Specific Defensives. Theres so much going on that its hard to keep track! Like B cells, and all the different types of T cells, and all the stuff they do and when they do it....its confusing! help!

2 TYPES OF IMMUNITY SAY WHAT ???

Hey guys its Tessa N!
alright, so I don't understand the difference between active immunity and passive immunity. When do both happen and what is their effect on the body ???
HEEELLPPPP

MUDDIE POINT

hey guys kelly here

so my muddiest point for this unit was the difference between the 1st and 2nd defense line

Muddiest Point!

Hi, Heidi here!

What I'm confused about is all the DEFINITIONS and what they DO. For example like what is BACTERIOPHAGE?? and PROPHAGE?? I'm always LOST when in class Mrs. Stein talks about this. Other things I get confused on are BINARY FISSION, PHAGOCYTE, ACTIVE/PASSIVE IMMUNITY, MACROPHAGE, and lastly HISTAMINES... I KNOW its a lot that I'm confused on but at least one thing being defined would be nice! THANKs!

p.s. Sorry I couldn't make it as beautiful and colorful as I wanted it, so that whoever reads it would be entertained as well. :) Somethings messed up with the program..... I guess. :(

MUDDY HOLLOW TRAIL

Hi! It's Eunice C! I had some problems logging in but I'm in now!
I thought this unit was a bit confusing learning about all the bacteria's, viruses, the cells defenses, immunity, etc... BUT, the most difficult part for me was understanding the nonspecific and specific defense against diseases. How do they differ?

DID I JUST HEAR YOU SAY MUDD-I-E-S-T POINT?!

HEY! Rachie here! :) Muddiest Point.... Let's see... Well, mine has to be about the Memory B/Memory T cells. I dont get the difference! :(

Muddiest Point

Hey! It's Kara S! So my muddiest point is an antigen the same thing as a pathogen? or does a pathogen turn into an antigen?

Obligate and faculative what?

Hey its Jessie! Im really confused about whats obligate aerobes, obligate anaerobes, and faculative anaerobes are. Can some one please explain that for me? Also whats the diference between them? Thanks!

It's Jarod!

At the start of class we turned in the unit packet pages 13-18. Those pages were about how bacteria grows and how some of the antibiotics we used had killed them in their tracks. That assignment lead us in to a talk on how some bacteria could live in the zone of inhibition(to the right). Even thought you can't see it there are tiny colonies of bacteria that are in that zone right now! These bacteria are resistant to that antibiotic. The way that they can live there is because ether went threw spontaneous mutation or conjugation. Those are some big words. I hope you took notes! After we did the DOD which was Tuberculosis. The agent was bacteria itself and it is highly contagious and it's a huge health concern. Then we did a little lab on how a girl fell of her bike and got infected with bacteria and went to the hospital. They tried many antibiotics on her and she got better. some were able to resist antibiotics A,C,D. I won't tell you the answer myself. All of the above concluded the day.

The next scribe is Mark.
