Question: Which of the following mutations is likely to have the most severe effect on a protein?

Options:

Correct Answer: Frameshift mutation

Solution:

Frameshift mutations can alter the reading frame of the genetic code, potentially leading to a completely nonfunctional protein.

Which of the following mutations is likely to have the most severe effect on a protein?

Correct Answer: Frameshift 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. Common types include point mutations, insertions, deletions, and frameshift mutations.
Step 3: Know what a frameshift mutation is. It occurs when nucleotides are added or removed from the DNA sequence in a number that is not a multiple of three.
Step 4: Realize that the genetic code is read in groups of three nucleotides (codons). A frameshift changes how these codons are read.
Step 5: Understand that a frameshift mutation can change many amino acids in a protein, potentially making it nonfunctional.
Step 6: Compare frameshift mutations to other mutations. Point mutations usually change only one amino acid, while frameshift mutations can affect the entire protein.
