Double Helix Definition Biology

Double Helix - Genome.gov

Double helix is the description of the structure of a DNA molecule. A DNA molecule consists of two strands that wind around each other like a twisted ladder. Each strand has a backbone made of alternating groups of sugar (deoxyribose) and phosphate groups. More Information

Double helix - Bio-Medicine

Double helix The term Double helix(pluralhelices) describes the structure of DNAas first published by James Watsonand Francis Crickin 1953. They showed that DNA is made up of two complementary, antiparallel strands of the bases Guanine, Adenine, Thymine, and Cytosine, covalentlylinked through phosphodiester bonds. More Information

Double-Helix Structure of DNA - ThoughtCo

Double helix is the biological term that describes the overall structure of DNA. Its double helix consists of two spiral chains of DNA. This double helix shape is often visualized as a spiral staircase. The twisting of DNA is the result of both hydrophilic and hydrophobic interactions between the molecules that comprise DNA and water in a cell. More Information

Nucleic acid double helix - Wikipedia

In molecular biology, the term double helix 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. More Information
