Summary Introduction
Introduction:
DNA or deoxyribonucleic acid is the hereditary material that is present in all the organisms. DNA acts as an organism’s blueprint that gives the instruction for which kinds of proteins each cell should make. Nearly all the cell in a human body contains the same copy of DNA.
