Aziz Sancar: Nobel Prize-Winning Turkish Photochemist Revolutionizing DNA Repair Understanding
Editor's Notes: "Aziz Sancar: Nobel Prize-Winning Turkish Photochemist Revolutionizing DNA Repair Understanding" have published today date
To understand why DNA repair is important, we must first understand what DNA is. DNA, or deoxyribonucleic acid, is a molecule that contains the instructions for an organism's development and characteristics. It is found in the nucleus of cells and is made up of four different types of nucleotides: adenine, thymine, guanine, and cytosine. These nucleotides are arranged in a specific order to create genes, which are the units of heredity.
