Explanation:

DNA is a genetic material that is found in all organisms humans as well as animals. All cells in the human body contain the same cells. All the DNA is situated in the nucleus of the cells where it is called nuclear DNA. It is also found in mitochondria but a very small quantity. DNA stored a code. These codes are in four forms as adenine, guanine, cytosine, and thymine. Surprisingly, DNA contains billions of bases and all these bases are the same in all human beings. DNA components make pair with each other such as T with and C with T and so on. These bases are attached with sugar and phosphate molecules.
