What do you know about the structure and function of chromosomes?

Chromosomes are a complex of DNA and proteins. DNA has the form of a double helix and consists of separate sections – genes, which are responsible for the synthesis of one cell protein and, therefore, for the development of a certain trait. In somatic cells there are 46 chromosomes, in gametes (sex cells) – 23 chromosomes.
