The genome

The genome is the set of genes of each living being. This genetic material consists of DNA (deoxyribonucleic acid), a long polymer formed of 4 types of nucleotides (symbolized by 4 letters of the alphabet) whose precise sequence in a specific order forms the genes.

It was in 2000 that researchers decoded the human genome, which they identified each of the letters of this alphabet which is linked together.

The genome can be considered as the book of life of the living being. It contains all the information concerning the development of this being, both physically and physiologically, its characteristics, and its reproduction.

The genome in each of our cells

Each living organism consists of at least one cell, up to several billion cells (as in humans). Each cell contains various elements including a nucleus that contains most of the genetic material, and organelles. Among those,
the mitochondria that provide cellular respiration also contain some of the genetic material.

The cells in turn constitute the tissues that constitute the organs, which are in turn hierarchized into devices (locomotor, digestive, etc.).
