Question

An immature stop codon leads to?

• A. Mutation
• B. Non-sense mutation
• C. Variation
• D. Intron

Answer 1

The correct option is B Non-sense mutation

In genetics, a point nonsense mutation is a point mutation in a sequence of DNA that results in a premature stop codon, or a point nonsense codon in the transcribed mRNA and formed usually nonfunctional protein product. the functional effect of a point nonsense mutation depends on the location of the stop codon within the coding DNA. Hence, an immature stop codon leads to a nonsense mutation in a particular protein.

So, the correct answer is option B.
