Question

reviewing dna mutations
identify the types of point mutations depicted:
leucine
valine
missense mutation
nonsense mutation
silent mutation

Explanation:

A missense mutation is a point mutation where a single nucleotide change results in a codon that codes for a different amino acid. In this case, the original DNA sequence (with a C) codes for Leucine, and after the mutation (to a G), it codes for Valine. A nonsense mutation would introduce a premature stop codon. A silent mutation would change the nucleotide but not the amino acid (due to codon degeneracy). Since the amino acid changed, it's a missense mutation.

Answer:

missense mutation
