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 ...

Researchers have revealed the structural mechanisms of a major DNA repair pathway in human cells. The research, published ...

The two strands of DNA form a 3-D structure called a double helix. When illustrated, DNA looks like a spiral ladder in which the base pairs are the rungs, and the sugar-phosphate backbones are the ...

The hydrogen bonds between the base pairs form the double helical structure of DNA. There is no exchange or sharing of electrons in hydrogen bonds as seen in covalent or ionic bonds. Hydrogen ...

DNA and RNA use the same five-carbon sugar, ribose, in their structure. The deoxy- means that on one side of the base pair, there's a place where another base pair can attach itself by way of a ...

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 ...

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 ...

Many crystal structures of DNA are in an A-DNA form. It has a shorter structure, with different numbers of base pairs per turn and tilt than B-DNA. A-DNA’s biological relevance has been greatly ...

DNA’s complexity and flexibility have made it hard, however, to analyze the detailed structure of its excited ... through single base pairs—the rungs in the double helix formed by links ...
