Question

Which is an example of a substitution mutation?

Answer 1

Answer:

The answer is C

Answer 2

Answer:

CAT - GGC - TAC mutates to CAT - GGC - TAG is the right answer

Explanation:

because substitution mutation is the change in the single base which result in change in codon which encode different amino acid  and protein sequence changes.

for example in this

CAT - GGC - TAC  encodes HGY protein

now after change in single nucleotide from C to G

CAT - GGC - TAG which encodes HG stop codon
