Which best matches a type of genetic material with its description?

DNA is the genetic material found in the nucleus of eukaryotic cells, so choice A correctly matches DNA with its location. Chromosomes contain genes rather than creating them. Nucleotides make up DNA, whose structure is a double helix; a gene is a section of DNA, not the name of the helix. Genes do not combine to form nucleotides.
