Question

A part of an mRNA has the sequence CCG. Which change to this sequence would indicate a missense mutation?

Answer 1

The codon CCG codes for Proline....just like A, B and C (A and B are the same so perhaps a typo)....all these codons (CCA, CCU, CCG and CCC) code for proline. The one that doesn't code for proline is the last one (D), CGG - this one codes for tryptophan.

You can check these on a codon table.

So your answer is D. CGG
