At school, it's often presented as a tidy double helix but scientists are revealing the varied and intricate shapes of DNA molecules.

The G4-DNA structure can therefore be involved in both the enhanced and impairment of transcription in active neurons, based on their activity, to enable different memory states. This mechanism ...

The nucleotides are connected through phosphodiester bonds, forming a long chain. In DNA, two complementary strands of nucleotides pair up through hydrogen bonds between the bases (A with T and G with ...

James Watson and Francis Crick revealed the structure of DNA — the genetic instructions in all living things — 70 years ago in the journal Nature. Watson and Crick could not have succeeded ...

In his 1968 book "The Double Helix," Watson alleged that he saw Franklin's photograph without her knowing and upon first glance he was able to spot DNA's double-helix structure, making it appear ...

DNA molecules supply the basic instructions that direct the life processes of all living things (except a few viruses). The DNA molecule contains information in a chemical code—the code of life.
