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 ...

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 ...

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 ...

But the challenge is daunting: Each RNA molecule is tightly bound to an assembly of proteins which creates a double helix, forming a protective coat that is difficult to manipulate. For the first ...

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 ...

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 ...
