Question

A genetic mutation resulted in a change in the mRNA sequence but the amino acid sequence and function of the protein were not changed. Which statement best describes the genetic mutation?
A- it was a silent mutation in a coding region of DNA that caused a change in the DNA of the organism
B- it was a nonsense mutation in a non-coding region of DNA that caused a change in the DNA of the organism
C-it was a nonsense mutation in a non-coding region of DNA that caused a change in the phenotype

Answer 1

I believe your answer would be A.) because silent mutations change the sequence of mRNA, but not the function. (Henceforth being called "silent")

Hope this helps!
