Much important confirmatory evidence on the genetic code has come from assessing changes in the amino acid sequence of mutant pr
oteins after a single base has been changed in the gene that encodes the protein. Which of the listed amino acid replacements would be consistent with the genetic code if the replacements were caused by a single base change? Which cannot be the result of a single-base mutation? Why? a. Phen Leu (e) llen Leu
b. Lysn Ala (f) Hisn Glu
c. Alan Thr (g) Pron Ser
