Jimena Jimenez · Answer 1

-nonsense mutation

Explanation:

Non-sense mutations can be described as mutations that to formation of a non-sense or stop codon in mRNA made from mutated gene. There are a total of 64 codons, out of which 61 code for specific amino acids and 3 codons act as stop codon or non-sense codons.

As these codons provide signal for termination of transcription, non-sense mutations lead to formation of a incomplete or truncated proteins due to premature termination of translation.

Thus, the correct answer is 'second option.'
