1) Genetics is a science that studies the laws of heredity and variability of living organisms.
2) DNA is a carrier of hereditary information, preserves it and passes it on to the next generation. .The molecule itself is like a spiral staircase. The "stair railings" are molecules of phosphate and deoxyribose, connected by "steps" - the nucleotides of adenine (A), guanine (G), thymine (T), cytosine (C).
3) DNA provides storage, transmission from generation to generation of genetic information in the form, which is a sequence of nucleotides.
