Nucleic Acids and the Genetic Material Problem Set 1

Problem 12: mRNA and protein coding



Under conditions where methionine must be the first amino acid, what protein would be coded for by the following mRNA?

5'-CCUCAUAUGCGCCAUUAUAAGUGACACACA-3'

A. pro his met arg his tyr lys cys his thr
B. met arg his tyr lys cys his thr
C. met arg his tyr lys
Initiation starts with the methionine codon, 5'-AUG. Reading in groups of three gives CGC for arginine, CAU for histidine, UAU for tyrosine, AAG for lysine, and UGA a stop codon that releases the peptide.
D. met pro his met arg his tyr lys cys his thr
E. arg his ser glu tyr tyr arg leu tyr ser
