Double Helix - The Definitive Guide | Biology Dictionary
Double helix is the term used to describe the shape of our hereditary molecule, DNA. This instantly recognizable structure consists of two strands of DNA twisted around one another and connected in the center by hydrogen bonding.

Nucleic acid double helix - Wikipedia
In molecular biology, the term double helix[1] refers to the structure formed by double-stranded molecules of nucleic acids such as DNA. The double helical structure of a nucleic acid complex arises as a consequence of its secondary structure, and is a fundamental component in determining its tertiary structure.

Discovery of DNA Double Helix: Watson and Crick - Nature
The 3-dimensional double helix structure of DNA, correctly elucidated by James Watson and Francis Crick. Complementary bases are held together as a pair by hydrogen bonds.

The Discovery of the Double Helix, 1951-1953
The discovery in 1953 of the double helix, the twisted-ladder structure of deoxyribonucleic acid (DNA), by James Watson and Francis Crick marked a milestone in the history of science and gave rise to modern molecular biology, which is largely concerned with understanding how genes control the chemical processes within cells.

Double Helix - National Human Genome Research Institute
Definition. Double helix, as related to genomics, is a term used to describe the physical structure of DNA. A DNA molecule is made up of two linked strands that wind around each other to resemble a twisted ladder in a helix-like shape.

Understanding the Double-Helix Structure of DNA - ThoughtCo
The double-helix shape allows for DNA replication and protein synthesis to occur. In these processes, the twisted DNA unwinds and opens to allow a copy of the DNA to be made. In DNA replication, the double helix unwinds and each separated strand is used to synthesize a new strand.

The Double Helix - Wikipedia
The Double Helix: A Personal Account of the Discovery of the Structure of DNA is an autobiographical account of the discovery of the double helix structure of DNA written by James D. Watson and published in 1968.

double helix | Learn Science at Scitable - Nature
The double helix describes the appearance of double-stranded DNA, which is composed of two linear strands that run opposite to each other, or anti-parallel, and twist together.

The structure of DNA
The double helix put genetics on a physical footing that would shed light on almost every aspect of modern biology and medicine.

DNA - Wikipedia
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.
