Unformatted text preview: What are the different steps (reactions) that lead to the attachment of an amino acid at the CCA terminus of a tRNA molecule? What are anticodons? Explain the degeneracy of the genetic code on the basis of how a single tRNA molecule is able to recognize multiple codons that specify a single amino acid. What are the steps involved in the initiation of protein synthesis? How does it differ in eukaryotic and prokaryotic cells? Describe the reactions involved in peptide bond formation and elongation of protein synthesis. How is protein synthesis terminated? Explain how streptomycin, tetracychin and erythromycin inhibit protein synthesis? What is a signal peptide? How does a nascent protein containing a signal peptide sequence traverse to the lumen of the endoplasmic reticulum? How does sorting of proteins destined for plasma membrane localization or secretion occur in a eukaryotic cell?...
