Question

The DNA sequence TTG is changed to TCG and produces a new protein. Which type of mutation is this?

Answer 1

A. Missense.

Step-by-step explanation:

Since the resulting nucleotide is offset from its initial sequence by only one parallel nucleotide we can definitely say it is Missense mutation. This sort of a mutation is known as a nonsynonymous mutation, there is only one direct substitution that occurs in the codon producing a different amino acid.

Answer 2

The answer is Missense. The amino acid is being replaced by another amino acid in the DNA sequence TTG changing to TCG and producing a new protein.
