What is DNA and What Role Does it Play in Our Bodies?

DNA, or deoxyribonucleic acid, is the genetic code that contains instructions for the development, functioning, growth, and reproduction of all living organisms. In our bodies, DNA plays a crucial role in determining our traits, such as eye color, hair texture, and susceptibility to certain diseases. It is like a blueprint for building and maintaining an organism. DNA is made up of nucleotides, which are composed of a sugar, a phosphate, and a nitrogenous base. These nucleotides pair up to form the famous double helix structure, which is responsible for the remarkable stability and perpetuation of genetic information.
