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 DNA. In this type of pairing, adenine ...

This base-to-base bonding is not random; rather, each A in one strand always pairs with ... ladder-like structure described above, another key characteristic of double-stranded DNA is its unique ...

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 Watson and Crick had solved the structure ...

Shown here is the structure ... pairs up with G. The sides of the DNA ladder consist of a long string of sugar and phosphate molecules, to which the bases are attached. Each sugar-phosphate-base ...

The original model of DNA structure created by Crick and Watson ... The two threads are held together by bonds between base pairs. There are four types of base - adenine, thymine, cytosine and ...

Crick had just learned of Chargaff's findings about base pairs in the summer ... This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations.

Later, in 1960, the discovery that an RNA molecule and a DNA molecule ... chemical structure with, in some cases, higher-order structures obtained through complementary base-pair folding.

In the double helix structure of DNA, thymine forms a base pair with adenine through two hydrogen bonds. This specific pairing is known as complementary base pairing and is essential for the stability ...

For the first time, researchers have filmed in real time the disassembly of DNA at the atomic scale. This strand separation is the first step in DNA replication. This breakthrough, published ...

The central part of each nucleosome (core particle) is a cylindrical structure (5.7 nanometers in height and 11 in diameter) ...
