More than 50 years passed before the significance of Miescher's discovery of nucleic acids was ... with each pair held together by hydrogen bonds, but the structure also reflected Chargaff's ...

This incredible array of functions derives from a startlingly simple code that specifies a hugely diverse set of structures ... bonds, and polar amino acids are capable of forming hydrogen ...

Nucleic acids ... 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 C) to form ...

These include wobble base pairs, such as G-U and I-A (inosine-adenine), which have a slightly different geometry and hydrogen bonding pattern. Non-Watson-Crick base pairs can play important roles in ...

DNA is fundamental to the biology of all life on Earth, but how many of us actually know what it is or what it's made of?

the structure of DNA was elucidated, revealing even more strikingly the crucial role of very basic organic compounds. It also revealed a way in which some compounds -- nucleic acids -- could ...
