Question

choose all of the statements that are true about the potential impact of missense mutations.

check all that apply

create nonfunctional proteins

produce proteins with altered function

have no impact on protein function

Explanation:

Analyze the nature of missense mutations

A missense mutation is a point mutation in which a single nucleotide change results in a codon that codes for a different amino acid.

Evaluate the potential impacts on protein function

• Create nonfunctional proteins: If the substituted amino acid is located at a critical site (such as the active site of an enzyme) or significantly alters protein folding, the resulting protein can become completely nonfunctional.
• Produce proteins with altered function: The substitution may change the protein's activity, substrate specificity, or stability, leading to an altered but still active function.
• Have no impact on protein function: If the substituted amino acid has similar chemical properties (conservative substitution) or is located in a non-essential region of the protein, there may be no detectable change in protein function.

Determine the correct choices

Since the question asks for "all of the statements that are true about the potential impact," and all three scenarios are biologically possible outcomes of a missense mutation, all three statements are correct.

Answer:

• Create nonfunctional proteins (Correct answer)
• Produce proteins with altered function (Correct answer)
• Have no impact on protein function (Correct answer)
