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.

The primary function of DNA is to store genetic information that is used to synthesize proteins, which perform a wide range of functions in living organisms. DNA also plays a critical role in the transmission of genetic traits from one generation to the next. 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 replication is the process by which a

The discovery of DNA dates back to the 19th century when Friedrich Miescher first isolated DNA from white blood cells in 1869. However, it wasn't until the 1950s that the structure of DNA was elucidated by James Watson, Francis Crick, and Rosalind Franklin using X-ray crystallography. DNA also plays a critical role in the

The Structure and Function of DNA

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.
