15. Why do many eukaryotic proteins start with a Met residue on the amino terminus? A. At the start of synthesis, only the Met tRNA can bind to the regulatory site on the small ribosomal subunit. B. Most proteins are soluble and the signal sequence always starts with a Met. C. The sulfur of Met forms a thioester linkage to the small ribosomal subunit during synthesis. D. The initiation codon also codes for Met. E. There is currently no accepted hypothesis for this observation. 16. Why is the genetic code said to be "degenerate"? A. The first base in a codon is the most important for coding, followed by the second base, and the third base is least important. B. Each amino acid can be specified by more than one codon. C. Fewer amino acids are coded by the four bases than was expected. D. The less complexity in an organism, the fewer codons are specified. E. The genetie.code deteriorates with each replication (generation), unless proofreading functions correct for error
