Your cells store DNA, protect it, copy it, repair it, and read selected parts of it when needed. Through these processes, DNA helps connect generations of cells.

DNA is an organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits.

Deoxyribonucleic acid, commonly known as DNA, serves as the fundamental molecular instruction set for all known forms of life. This molecule is present in nearly every cell of every living organism. It is the blueprint that guides the construction and operation of biological systems.

DNA, or deoxyribonucleic acid, is the molecular backbone of life. Found in nearly every cell of living organisms, it’s a long, twisted ladder-like structure called a double helix. DNA’s primary job is to store and transmit genetic information —the recipe for building and maintaining an organism.

DNA is a molecule found in most cells that holds each person’s unique genetic code. It is responsible for coding proteins, which are essential to cell growth and development.

DNA carries instructions that your cells can read and translate into proteins. These proteins help your body do everything it needs to function — from how your organs work to how you look.

DNA does more than store your genetic code. Learn how it builds proteins, copies itself, regulates genes, and drives the variation that makes every organism…

All known cellular life and some viruses contain DNA. The main role of DNA in the cell is the long-term storage of information. It is often compared to a blueprint, since it contains the...

Subsequent research confirmed the Watson and Crick model of DNA replication and showed that DNA carries the genetic information for reproduction of the entire cell. All of the genetic information in a cell was initially thought to be confined to the DNA in the chromosomes of the cell nucleus.

DNA's unique structure enables the molecule to copy itself during cell division. When a cell prepares to divide, the DNA helix splits down the middle and becomes two single strands.
