The scientist who discovered hybridization and the "other" double helix describes what it meant to biology. By Alexander Rich Fifty-two years ago I was venturing to the basement of Cal Tech chemistry ...

RNA Timeline: A History in Hybridization and Structure Alexander Rich and David Davies discover the double-stranded RNA helix and show that polyribo U and polyribo A hybridize spontaneously.6 Ben Hall ...

Its twisted, double-helix structure is one of the most iconic images in the scientific world. RNA gets a little less attention than DNA, but it is no less important. RNA takes the genetic ...

Later, in 1960, the discovery that an RNA molecule and a DNA molecule could form a hybrid double helix was the first experimental demonstration of a way in which information could be transferred ...

who first proposed the double helix structure of DNA. In this type of pairing, adenine (A) forms two hydrogen bonds with thymine (T) in DNA or uracil (U) in RNA, while guanine (G) forms three hydrogen ...

Certain DNA sequences can form structures other than the canonical double helix. These alternative DNA conformations—referred ...

DNA and RNA are composed of nucleotides that are ... In double-stranded DNA, the molecular double-helix shape is formed by two linear sugar-phosphate backbones that run opposite each other and ...

The message encoded in the messenger RNA is read by structures ... The twisted double strand structure -- the famed double helix -- unwinds and the strands separate. The nucleotides (A, T, G ...

During DNA replication, the double helix unwinds, and each strand serves as a template ... Several antiviral and anticancer drugs target the incorporation of adenine into DNA or RNA. For example, some ...
