Lecture 20 Biol 002 3-07-07 Reading: Chapter 15: 302-305, 309-316 Topic: translation, the process of protein synthesis _________________________________________________________________________ genetic code problem: Fig. 14.23: how could the gene for beta globin have been changed to give sickle-cell anemia? __________________________________________________________________________ I. Protein synthesis ( translation of mRNA) machinery: What is the structure and role of each of the following components ( figs. 15.2-15.4, 15.14)? mRNA ribosomes (Fig. 15.2, 15.3) transfer RNAs (tRNAs) (Fig. 15.14) anticodon (Fig. 15.11) amino acid attachment site aminoacyl-tRNA sythetases (Fig. 15.14) Why is it true that the fidelity of protein synthesis ultimately depends on these enzymes? II The stages of protein synthesis (pages 310-312) How do each of the following occur? Initiation (Fig. 15.15) What are the roles of: mRNA ribosomal small subunit "initiator" tRNA carrying methionine large ribosomal subunit
