contains the majority of the cell's genetic material in the
form of multiple linear DNA molecules organized into structures called
chromosomes. Each human cell contains roughly two meters of DNA.

are a threadlike structure of nucleic acids and protein
found in the nucleus of most living cells, carrying genetic information in the
form of genes.

that understating on society past and present. Specific to indicator C – recognize that the nucleus of a
cell contains genetic information and identify the relationship among chromosomes, genes, and DNA in
transmitting genetic information.
