Question 12 • PA Human Anatomy & Physiology A 2026-2027 SMITH IC

Which statement best describes the relationship between proteins and nucleic acids?

Answer
A
Nucleic acids are assembled from the amino acids of proteins.
B
Nucleic acids have the code that determines which proteins are made.
C
Proteins provide the backbone from which nucleic acids are made.

Explanation

Nucleic acids such as DNA contain genetic instructions that specify the order of amino acids in proteins. Cells use those instructions to make particular proteins, so the best statement is that nucleic acids have the code that determines which proteins are made. Proteins are not assembled from amino acids of nucleic acids, nor do they form the backbone of nucleic acids.
