Question: Which mutation can result in a premature stop codon?

Options:

  1. Silent mutation
  2. Missense mutation
  3. Nonsense mutation
  4. Frameshift mutation

Correct Answer: Nonsense mutation

Solution: 

A nonsense mutation can result in a premature stop codon, leading to truncated proteins.

Questions & Step-by-Step Solutions

Which mutation can result in a premature stop codon?
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 more.
  • Step 3: Focus on nonsense mutations. A nonsense mutation is a specific type of point mutation.
  • Step 4: Know what a stop codon is. A stop codon is a sequence in the DNA that signals the end of protein synthesis.
  • Step 5: Understand how a nonsense mutation works. It changes a regular codon (which codes for an amino acid) into a stop codon.
  • Step 6: Realize the effect of a premature stop codon. This causes the protein to be made shorter than it should be, which can affect its function.
