Question

A mouse had a gene sequence of GTT coding for leucine, an amino acid. mutation in this gene led to the formation of GTG. However, the amino acid formed was leucine, despite the mutation. This is a mutation for the mouse

Answer 1

Answer:

1- substitution.

2- neutral.

Explanation:

The change in the genetic sequence of the organisms known as mutation. Mutations might be sudden and heritable in nature. spontaneous mutation and induced mutation are types of mutation.

A change that causes a change in single base pair of a gene sequence is called substitution mutation. The original leucine sequence is GTT and the mutated sequence is GTG. Thus T has been substituted by G.

Mutation can be beneficial, detrimental or neutral. The neutral mutation is that does not affect the physical change. Both GTT and GTG code for the same amino acid so it would be neutral.
