Question

Quizplus · Accepted Answer

Genes are the specific sequences of DNA nucleotides that code for specific traits or characteristics in an organism. Chromosomes are made up of genes, and each gene is responsible for encoding the instructions for the production of a particular protein or RNA molecule. While DNA is the macromolecule that carries genetic information and nucleotides are the building blocks of DNA, neither of these options completely categorize the units on chromosomes that code for genetic information. Therefore, the most accurate answer is B, genes.
