Question

A random mutation occurs and the GGA codon is changed to GGU. What effect does this substitution have on the amino acid being called for? Explain your answer.

Answer 1

Answer:

Instead of arginine codon, proline condon would be coded.

Explanation:

GCA encodes codes for glycine while on the other hand codon to GGU, GGC, or GGG encodes for glycine.

This substitution will lead to generation of complementary code “Proline” in the complementary mRNA or DNA strand.  

The codon CCT, CCC, CCA, CCG encodes for proline. If this mutation would not have occurred then Arginine would have been encoded in the complementary codon  with base structure of CGT, CGC, CGA, CGG
