Question

a point mutation changes the dna sequence cga to cgt, but the same protein is still produced. which point mutation occurred?
onsense
missense
silent
frameshift

Explanation:

A silent mutation is a type of point - mutation where the change in the DNA sequence does not result in a change in the amino - acid sequence of the protein being produced. Since the same protein is produced despite the change from CGA to CGT, this is a silent mutation. Nonsense mutations create stop codons, missense mutations change the amino - acid, and frameshift mutations shift the reading frame of the genetic code.

Answer:

C. silent
