Have you ever heard the expression “you carry it in your DNA”? DNA is everywhere, in the cinema, on TV, in the newspapers… But what is DNA?
DNA (deoxyribonucleic acid) is the molecule that encodes the information necessary for the construction and functioning of an organism. We could say that it is the instruction manual for living things.
DNA is the molecular material transmitted from one generation to the next, meaning that it is inherited from parents to children. When we say that a characteristic (or “character”) is hereditary, such as eye colour, what we are saying is that the information that determines the color of someone’s eyes is encoded in their DNA and, therefore, is transmitted from one generation to the next.
Indeed, it was bacteria that allowed scientists to discover that the material passed on from one generation to the next was DNA.
Scientists also use other organisms such as Drosophila (fruit fly) or zebrafish to carry out experiments. These organisms are called model organisms.
Discover from the rhythm of rap that we are made of DNA.
