Double-stranded deoxyribonucleic acid

DNA (deoxyribonucleic acid) A double-stranded molecule held together by weak bonds between base pairs of nucleotides that encodes genetic information. The base sequence of each single strand can be deduced from that of its partner since base pairs form only between the bases A and T and between G and C.

Nucleic Acid. A nucleic acid is a natural polynucleotide. It is a sugar-phosphate chain with purine and pyrimidine bases attached to it, as shown in Chart 10. If the sugar is deoxyribose and the pyrimidine bases are cytosine and thymine, the nucleic acid is deoxyribonucleic acid, DNA if the sugar is ribose, and the pyrimidine bases are (mostly) cytosine and uracil, the nucleic acid is ribonucleic acid, RNA. The sequence of bases may appear arbitrary and random, but it constitutes a meaningful code (see Code Word). In double-stranded nucleic acids,... 

DNA Deoxyribonucleic acid is the repository of hereditary characteristics. The most commonly described form of DNA is the double-stranded form, arranged as a helix. Chromosomes are composed of double-stranded DNA. So called DNA fingerprinting offers a basis for evaluating the probability that blood, hair, semen or tissue samples originate from a given person, and thus offers a forensic tool as well as a means to determine lineages of humans and animals... 

DNA (deoxyribonucleic acid) The basic genetic material found in all living cells (and some viruses), providing the blueprint (i.e. genes) for construction of proteins. DNA is composed of sugars, phosphates, and bases arranged in a double helix, a double stranded, chain-like molecules composed of nucleotide base pairs. 

DNA Deoxyribonucleic acid, the substance within cells that carries the recipe for the organism and is inherited from parents. A normally double-stranded molecule made up of deoxyadenosine, deoxycytidine, deoxyguanosine, and deoxythymidine. 

Deoxyribonucleic acid (DNA) carries the genetic information of all cellular forms of life. DNA is usually found as a double helix, in which the nucleoside bases of the single strands are stacked upon each other, forming strong hydrogen bonds with... 

During the past half a century, fundamental scientific discoveries have been aided by the symmetry concept. They have played a role in the continuing quest for establishing the system of fundamental particles [7], It is an area where symmetry breaking has played as important a role as symmetry. The most important biological discovery since Darwin s theory of evolution was the double helical structure of the matter of heredity, DNA, by Francis Crick and James D. Watson (Figure 1-2) [8], In addition to the translational symmetry of helices (see, Chapter 8), the molecular structure of deoxyribonucleic acid as a whole has C2 rotational symmetry in accordance with the complementary nature of its two antiparallel strands [9], The discovery of the double helix was as much a chemical discovery as it was important for biology, and lately, for the biomedical sciences.
