Each chromosome consists of a single very long DNA molecule, and each gene on the chromosome is a particular segment of that DNA. The instructions for forming species' characteristics are carried in DNA. All cells in an organism have the same genetic content, but the genes used (expressed) by the cell may be regulated in different ways. Not all DNA codes for a protein; some segments of DNA are involved in regulatory or structural functions, and some have no as-yet known function.

Items associated with this NGSS statement in this project (Evolution) and other key ideas
RH019003	The way DNA and proteins are related is that DNA provides information for making proteins.
041003	Genes are segments of DNA molecules.
022003	If GFP (green fluorescent protein), is found only in muscle cells of a frog, it is because the GFP gene is turned on only in those cells. (Choose sound reasoning to justify why given evidence supports a claim.)
