   Deoxyribonucleic 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.

   3 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.

   Deoxyribonucleic acid, or DNA, is a biological macromolecule that carries hereditary information in many organisms. DNA is necessary for the production of proteins, the regulation, metabolism, and reproduction of the cell. Large compressed DNA molecules with associated proteins, called chromatin, are mostly present inside the nucleus. Some cytoplas...

   DNA was isolated and discovered chemically before its functions became clear. DNA and its related molecule, ribonucleic acid (RNA), were initially identified simply as acidic molecules that were present in the nucleus. When Mendel’s experiments on genetics were rediscovered, it became clear that heredity was probably transmitted through discrete pa...

   When its definitive role in heredity was established, understanding DNA’s structure became important. Previous work on protein crystals guided the interpretation of crystallization and X-Ray differaction of DNA. The correct interpretation of diffraction data started a new era in understanding and manipulating genetic material. While initially, scie...

   As microscopes started to become more sophisticated and provide greater magnification, the role of the nucleus in cell division became fairly clear. On the other hand, there was the common understanding of heredity as the ‘mixing’ of maternal and paternal characteristics, since the fusion of two nuclei during fertilization had been observed. Howeve...
