Nucleic Acids and the Genetic Material Problem Set 1
Problem 10: Protein amino acids from translated mRNA
A messenger acid is 336 nucleotides long, including the initiator and termination codons. The number of amino acids in the protein translated from this mRNA is:A 999B 630
C 330
D 111
A messenger RNA of 336 nucleotides, including initiator and termination codons has 333/3 actual codons that determine amino acids The initiator codon is included since it codes for methionine (AUG) but the final three bases or termination codon does not specify an amino acid. Thus there are 336-3 codons, which would incorporate 111 amino acids into a protein.E 110
