DNA - Wikipedia
WEBDeoxyribonucleic acid ( / diːˈɒksɪˌraɪboʊnjuːˌkliːɪk, - ˌkleɪ -/ ⓘ; [1] DNA) is a polymer composed of two polynucleotide chains that coil around each other to form a double helix. The polymer carries genetic instructions for the development, functioning, growth and reproduction of all known organisms and many viruses.
DNA | Definition, Discovery, Function, Bases, Facts, & Structure
WEB2 days ago · DNA, organic chemical of complex molecular structure found in all prokaryotic and eukaryotic cells. It codes genetic information for the transmission of inherited traits. The structure of DNA was described in 1953, leading to further understanding of DNA replication and hereditary control of cellular activities.
DNA - Simple English Wikipedia, the free encyclopedia
WEBDNA, short for deoxyribonucleic acid, is the molecule that contains the genetic code of organisms. This includes animals, plants, protists, archaea and bacteria. It is made up of two polynucleotide chains in a double helix. DNA is in each cell in the organism and tells cells what proteins to make. Mostly, these proteins are enzymes.
DNA replication - Wikipedia
WEBIn molecular biology, DNA replication is the biological process of producing two identical replicas of DNA from one original DNA molecule. DNA replication occurs in all living organisms acting as the most essential part of biological inheritance .
Nuclear DNA - Wikipedia
WEBNuclear DNA is known as the molecule of life and contains the genetic instructions for the development of all eukaryotic organisms. It is found in almost every cell in the human body, with exceptions such as red blood cells. Everyone has a unique genetic blueprint, even identical twins. [7]
Nucleic acid - Wikipedia
WEBDeoxyribonucleic acid (DNA) is a nucleic acid containing the genetic instructions used in the development and functioning of all known living organisms. The chemical DNA was discovered in 1869, but its role in genetic inheritance was not demonstrated until 1943. The DNA segments that carry this genetic information are called genes.
DNA synthesis - Wikipedia
WEBDNA synthesis is the natural or artificial creation of deoxyribonucleic acid (DNA) molecules. DNA is a macromolecule made up of nucleotide units, which are linked by covalent bonds and hydrogen bonds, in a repeating structure.
Genomic DNA - Wikipedia
WEBGenomic DNA. Genomic deoxyribonucleic acid (abbreviated as gDNA [1]) is chromosomal DNA, in contrast to extra-chromosomal DNAs like plasmids. Most organisms have the same genomic DNA in every cell; however, only certain genes are active in each cell to allow for cell function and differentiation within the body.
The structure of DNA
WEBOct 9, 2019 · None of this stopped Watson and Crick from speculating about how the components of the DNA molecule — the four nucleotide bases adenine, guanine, thymine and cytosine, connected to a backbone of ...
Nucleic acid - DNA, Genes, Molecules | Britannica
WEBNucleic acid - DNA, Genes, Molecules: DNA is a polymer of the four nucleotides A, C, G, and T, which are joined through a backbone of alternating phosphate and deoxyribose sugar residues. These nitrogen-containing bases occur in complementary pairs as determined by their ability to form hydrogen bonds between them.
