A liver cell and a cheek cell have the same chromosomes. The only cells in the human body that do not contain 46 chromosomes are reproductive cells, which only contain 23 chromosomes, according to the National Human Genome Research Institute.
Each chromosome consists of proteins known as histones and a molecule of deoxyribonucleic acid, or DNA, states the National Human Genome Research Institute. The paired nature of chromosomes, and their unique structure, allows for cells to effectively divide, creating new cells to replace dying ones. While each cell contains all the DNA required to create the human the cheek and liver cells make up, only certain chromosomes are "switched on," allowing the chromosomes to create different cells with different functions.
