We apologize for Proteopedia being slow to respond. For the past two years, a new implementation of Proteopedia has been being built. Soon, it will replace this 18-year old system. All existing content will be moved to the new system at a date that will be announced here.

Base pairing

From Proteopedia

Jump to: navigation, search

Base pairing describes how pairs of nucleobases from hydrogen bonds in a co-planar arrangement. Most base pairs show two or three hydrogen bonds. Canonical Watson-Crick base pairs are between guanine and cytosine, and between adenine and thymine (or uracil) and are common in double helical nucleic acid structures. Other base pairs also exist and have a role in forming more diverse structures.
