Detailed explanation-1: -Nearly every cell in a person’s body has the same DNA. Most DNA is located in the cell nucleus (where it is called nuclear DNA), but a small amount of DNA can also be found in the mitochondria (where it is called mitochondrial DNA or mtDNA).
Detailed explanation-2: -When we talk about our genome-all the DNA in our cells-we speak in the singular. But over the course of decades, it has become clear that the genome doesn’t just vary from person to person. It also varies from cell to cell. The condition is not uncommon: We are all mosaics.
Detailed explanation-3: -All of a person’s cells contain the same set of genes (see more on genes). However, each cell type “switches on” a different pattern of genes, and this determines which proteins the cell produces. The unique set of proteins in different cell types allows them to perform specialized tasks.
