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:

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

A mutation is defined as a change in the genetic sequence of an organism. The deletion, substitutions, or insertion can result in the mutation and affect the polypeptide formed.

The substitution of single nucleotide will not affect the nucleotide.

The codons are the set of three nucleotides, which code for a specific amino acid.

In the given codon, GGA, it is randomly mutated into GGU.

GGA codes for Glycine. The codons GGT, GGC, and GGG will also code for the Glycine amino acid.

The substitution of GGA to GGU will have no effect because the codon GGu also codes for the Glycine.

Thus, T and U are the nitrogenous bases present in the DNA and RNA respectively, which interchange during the replication process.
