translation

October 31-November 4

In molecular biology on Monday and Wednesday, Dr. Peng lectured about translation in prokaryotes and eukaryotes. He discussed the structure of tRNAs as well as tRNA charging by class I and class II aminoacyl-tRNA synthetases. We also learned about ribosome structure and translation initiation, elongation, and termination.

In biochemistry on Tuesday and Thursday, Dr. Popescu discussed lipids, including sections on the biological roles of lipids and structure and properties of storage, membrane, and signaling lipids. We learned about all 6 classes of lipids – fatty acids, triacylglycerols, wax esters, glycerophospholipids, sphingolipids, and isoprenoids. On Tuesday in bacterial physiology, we learned about bacterial two-component signaling systems such as the Arc, Nar, Che, Pho, Bvg, Agr, Spo, PhoQ/PhoP, and EnvZ/OmpF systems. We also began to discuss microbial communities and environmental stresses such as heat shock response, SOS response, and oxidative stress responses.

Bacterial genetics lab was cancelled on Friday because the Sanger sequencing results weren’t ready. We had planned to do computer analysis of the results.
