The strands are bound with hydrogen bonds. Adenine bases are always joined with thymine bases, and cytosine bases are always joined with guanine bases. This is in accordance with Chargaff’s rules. The DNA double helix is right-handed.

WebThe 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. WebChromosomal DNA consists of two DNA polymers that make up a 3-dimensional (3D) structure called a double helix. In a double helix structure, the strands of DNA run antiparallel, meaning the 5’ end of one DNA strand is parallel with the 3’ end of the other DNA strand.
