Discover how Francis Crick and James Watson transformed genetics by discerning DNA's structure, This video presents the basics of DNA, the chemical that underlies life on Earth. Encyclopdia Britannica, Inc., abbreviation of, organic chemical of complicated molecular structure that is found in all prokaryotic and eukaryotic cells and in numerous infections.

A quick treatment of DNA follows. For complete treatment, see genetics: DNA and the hereditary code. The chemical DNA was very first discovered in 1869, but its function in hereditary inheritance was not shown till 1943. In 1953 James Watson and Francis Crick, aided by the work of biophysicists Rosalind Franklin and Maurice Wilkins, determined that the structure of DNA is a double-helix polymer, a spiral including 2 DNA hairs wound around each other.

Each hair of a DNA particle is made up of a long chain of monomer nucleotides. The nucleotides of DNA consist of a deoxyribose sugar molecule to which is connected a phosphate group and among 4 nitrogenous bases: two purines (adenine and guanine) and two pyrimidines (cytosine and thymine). The nucleotides are collaborated by covalent bonds between the phosphate of one nucleotide and the sugar of the next, forming a phosphate-sugar backbone from which the nitrogenous bases protrude.

e., adenine bonds only with thymine, and cytosine only with guanine.  Find Out More Here 's DNA origami and its future application in medical diagnostics, drug shipment, tissue engineering, energy, and the environment, DNA origami, established by American computer system scientist and bioengineer Paul Rothemund, involves folding DNA to create various shapes and structures, which may serve to clinical examinations in a wide variety of fields.

A section of DNA that codes for the cell's synthesis of a particular protein is called a gene. DNA replicates by separating into two single strands, each of which works as a design template for a brand-new hair. The brand-new strands are copied by the very same principle of hydrogen-bond pairing between bases that exists in the double helix.

This "semiconservative" replication is the key to the stable inheritance of hereditary characteristics. The initial proposition of the structure of DNA by James Watson and Francis Crick, which was accompanied by a suggestion on the ways of duplication. Encyclopdia Britannica, Inc. Within a cell, DNA is arranged into dense protein-DNA complexes called chromosomes.
