Question

A mutation that changes a codon specifying one amino acid to a termination codon is called a

• A. missense mutation
• B. transition mutation
• C. non-sense mutation
• D. frameshift mutation

Answer 1

The correct option is C non-sense mutation

A mutation in which a codon specifying one amino acid changes to termination codon is called as non-sense mutation.

Missense mutation is a single nucleotide change leads to a codon that codes for a different amino acid.

Transition mutation is a single nucleotide change in which a purine nucleotide changes to another purine, or a pyrimidine nucleotide changes to another pyrimidine.

Frameshift mutation is a genetic mutation caused by a deletion or insertion in a nucleotide sequence such that it shifts the way the sequence is read.
