-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
