Explanation:

Genes are specific nucleotide segments within DNA that carry genetic information. DNA molecules, along with associated proteins, tightly coil and condense to form chromosomes, which are the structures that hold genetic material in cells. The other options incorrectly reverse the hierarchical relationships between these three structures.
