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: -All living things have DNA within their cells. In fact, nearly every cell in a multicellular organism possesses the full set of DNA required for that organism.
Detailed explanation-3: -Definition. Ribonucleic acid (abbreviated RNA) is a nucleic acid present in all living cells that has structural similarities to DNA.
Detailed explanation-4: -Not every cell in our bodies actually contain DNA. There is typically a lack of DNA in our mature red blood cells and cornified cells which are found in hair, skin, and our nails. These cells don’t contain a nucleus. It turns out, our red blood cells are actually trained to destroy their cells nuclei.
