Bacteria



Hey guys, it's Maggie!
Today in class we went over quite a few slides on a powerpoint; mostly about bacteria. We learned the "Classification of Prokaryotes", which includes eubacteria and archeabacteria. We went over the three different shapes of bacteria. These include: bacilli (rod-shaped), cocci (spherical), and spirilla (corkscrew). Last but not least, we learned about binary fission and conjugation. Binary fission is when the DNA replicates and the cell divides in half. Cojugation is when a cell exchanged genetic material across a hollow bridge to another cell. At the end of class, we watched a movie that talked about fatal bacteria including anthrax. We have a quiz tomorrow so I hope everybody studies!
