Question: What is a common consequence of a frameshift mutation?

Options:

Correct Answer: A premature stop codon

Solution:

A frameshift mutation often results in a premature stop codon, leading to truncated proteins.

What is a common consequence of a frameshift mutation?

Step 1: Understand what a frameshift mutation is. It happens when DNA is added or removed, changing the way the genetic code is read.
Step 2: Realize that DNA is read in groups of three letters called codons, which each code for an amino acid.
Step 3: Know that a frameshift changes the grouping of these codons, which can lead to different amino acids being made.
Step 4: Recognize that this change can create a stop codon too early in the sequence.
Step 5: Understand that a premature stop codon means the protein is cut short, resulting in a truncated protein that may not work properly.
