Where DNA present in cell?

Researchers refer to DNA found in the cell's nucleus as nuclear DNA. An organism's complete set of nuclear DNA is called its genome. Besides the DNA located in the nucleus, humans and other complex organisms also have a small amount of DNA in cell structures known as mitochondria.

Moreover, how much DNA is in one cell of a human?

Genes are composed of DNA, and it is predicted that there are over 3 billion basepairs in the human genome. Humans have approximately 10 trillion cells, so if you were to line all of the DNA found in every cell of a human body it would stretch from the earth to the sun 100 times!

Is the DNA the same in every cell?

All the cells in a person's body have the same DNA and the same genes. However, the difference between cells in different tissues and organs is that the "expression" of the genes differs between cells. Expression means that the message from the DNA is being copied and made into protein.

Which cells don t have DNA?

Flavia Facio, M.S.: Red blood cells do not have a nucleus, so they do not have DNA. Hemoglobin can be made by other cells (like cells in the bone marrow) that have DNA that codes (or instructs) for the protein hemoglobin. But they themselves do not have DNA and so cannot make any proteins.
