Question

identify the types of point mutations depicted. glycine glycine lysine missense mutation missense mutation nonsense mutation nonsense mutation silent mutation silent mutation done done

Explanation:

A silent mutation occurs when a change in the DNA sequence does not result in a change in the amino - acid sequence of the protein. In the first example, the DNA triplet changes from GGC to GGA, but both code for glycine. In the second example, the change in the DNA sequence from AAG does not result in a change in the amino - acid (lysine), so it is also a silent mutation.

Answer:

First part: C. silent mutation
Second part: C. silent mutation
