Imagine that one side of a dna molecule has the following chemical base sequence: c-g-a-a-t which of the following represents a genetic mutation of the sequence? c-g-a-a-t or c-g-a-t-t

The correct option is C-G-A-T-T

Genetic mutation is permanent change in either of the two:

a) Single building block ( a unit base pair, A, G, C, T)

OR

b) Change in the Codon (triple base pair like AGG TCT etc.) or a large part of the chromosome.

In this question there is a change in single building block and thus, it is a genetic mutation.

i believe the correct answer from the choices listed above is the first option. the scientists need to look at the   validity of data, claims, hypotheses, and observations before  developing an argument. they base their arguments on facts that are present and they make sure they have proofs.
