Question: Which of the following mutations is most likely to result in a nonfunctional protein?

Options:

Correct Answer: Nonsense mutation

Solution:

A nonsense mutation introduces a premature stop codon, leading to a truncated and often nonfunctional protein.

Which of the following mutations is most likely to result in a nonfunctional protein?

Correct Answer: nonsense mutation

Step 1: Understand what a mutation is. A mutation is a change in the DNA sequence.
Step 2: Learn about different types of mutations. There are several types, including point mutations, insertions, deletions, and nonsense mutations.
Step 3: Focus on nonsense mutations. A nonsense mutation is a specific type of mutation that changes a DNA sequence so that it creates a stop codon.
Step 4: Know what a stop codon does. A stop codon signals the end of protein synthesis, meaning the protein production stops.
Step 5: Realize the effect of a premature stop codon. If a stop codon appears too early in the sequence, the resulting protein is shorter than it should be, which can make it nonfunctional.
Step 6: Conclude that nonsense mutations are likely to result in nonfunctional proteins because they lead to truncated proteins.
