Erwin Chargaff's groundbreaking research, which showed that DNA base pairs had a complementary relationship, laid the foundation for James Watson's and Francis Crick's DNA model. When word spread that ...

(Image: Wikimedia Commons, CC SA 3.0) The most common type of base pairing is the Watson-Crick base pair, named after James Watson and Francis Crick, who first proposed the double helix structure of ...

He added that to the model, so that matching base pairs interlocked in the middle of the double helix to keep the distance between the chains constant. Watson and Crick showed that each strand of ...

The landmark ideas of Watson and Crick relied heavily on the work of other ... components of a single nucleotide (phosphate-sugar-base); the first to discover the carbohydrate component of RNA ...

The left-handed Z-DNA double helix is held together by traditional Watson-Crick base pairs, but unlike righthanded B-DNA, which has major and minor grooves between the twists of its sugar-phosphate ...
