DNA is composed of four nucleotide bases - Adenine (A), Guanine (G), Cytosine (C), and Thymine (T) - which are paired in a specific manner to form the rungs of the DNA ladder. The sugar molecule deoxyribose and phosphate groups make up the backbone of the DNA. The sequence of these nucleotide bases determines the genetic information encoded in the DNA molecule.
DNA replication is the process by which a cell makes an exact copy of its DNA before cell division. Transcription is the process by which the genetic information in DNA is copied into a complementary RNA molecule. adn-344.mp4
DNA (Deoxyribonucleic acid) is a molecule that contains the genetic instructions used in the development and function of all living organisms. It is often referred to as the "building blocks of life" or the "genetic blueprint" of an organism. DNA is made up of two strands of nucleotides that are twisted together in a double helix structure. DNA is composed of four nucleotide bases -
