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 ...

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 ...

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 ...

"Being RNA-guided makes it relatively easy to reprogram ... "dual-guide system," interacting with both strands of the DNA double helix to home in on their target sequences, which should ensure ...

In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with C) to form the iconic double helix structure. RNA is usually single-stranded but ...

A new method for mapping torsion provides insights into the ways that the genome responds to the torsion generated by RNA polymerase II.
