(Note: This question requires the use of a coding dictionary to translate the genetic code.) A region within an mRNA molecule has the base sequence 5’- … CAG CAU GGG … -3’ . What is the corresponding amino acid sequence in the polypeptide?

a. Asp – Tyr – Gly

b. Gln – His – Gly

c. Val – Val - Pro

d. Pro – Met – Leu

e. Pro – Lys – Gly

Solution

b. Gln – His – Gly.

CAG codes for amino acids Glasgow. CAU codes for His and GGG codes for Gly.
