3.13 understand hat the nucleus of a cell contains chromosomes on which genes are located

Okay so basically every cell contains a nucleus, every nucleus contains chromosomes (humans are diploid and have 46 chromosomes, except for sex cells which are haploid and have 23). Each chromosome is made up of a long coil of DNA. DNA can be sectioned, a small section of DNA is known as a gene.
