What term describes the segments of DNA that carry genetic information on chromosomes?

Explanation:
Genetic information on a chromosome is carried by genes, which are specific segments of DNA that contain the instructions to produce RNA or a protein. Genes are the functional units of heredity and are located along chromosomes. Within a gene, exons are the coding sections that determine the amino acid sequence, while introns are noncoding regions that are spliced out during processing. Chromosomes house many genes, but not all DNA on a chromosome codes for a gene. Since the question is about the segments that carry genetic information, the term that fits best is genes.
