Question

Quizplus · Accepted Answer

A gene is a section of DNA that contains the instructions needed to make a functional protein. The sequence of nucleotides in the gene determines the sequence of amino acids in the protein. Proteins are not composed of DNA or amino acids themselves, but rather they are made up of chains of amino acids. Therefore, option A is the most accurate statement regarding genes, DNA, and proteins.

B) A gene is composed of DNA, not amino acids. 
C) DNA is the blueprint for genes, but genes themselves are not composed of amino acid sequences. 
D) This statement is not accurate as genes are composed of nucleotides, not amino acids. 
E) This statement is also not accurate as DNA and amino acids are two different types of molecules.
