The Functional Units of DNA That Contain the Instructions for Making

Question

The functional units of DNA that contain the instructions for making one or more proteins are
A) chromosomes.
B) genes.
C) ribosomes.
D) codons.
E) RNA.

Accepted Answer

Genes are the functional units of DNA that contain the instructions for making one or more proteins. Chromosomes are larger structures made up of multiple genes. Ribosomes and RNA are involved in protein synthesis but are not functional units of DNA. Codons are sequences of nucleotides that specify particular amino acids in a protein, but they are not themselves functional units of DNA.
