Chemical structure of guanine, showing its double-ring purine structure and the functional groups involved in hydrogen bonding with cytosine. (Image: Public Domain) Guanine has the chemical formula ...

In DNA, cytosine pairs with guanine through three hydrogen bonds, forming a stable base pair. The sequence of these base pairs along the DNA strand encodes genetic information. During DNA replication, ...

The hydrogen bonds are made as follows : purine position ... then on these assumptions the other member must be thymine ; similarly for guanine and cytosine. The sequence of bases on a single ...

It consists of just a few kinds of atoms: carbon, hydrogen, oxygen ... thymine (T), adenine (A), cytosine (C), and guanine (G). These bases are the rungs of the DNA ladder.

and guanine binds to cytosine (G-C). The researchers believe that these new structures "are created due to the formation of hydrogen bonds between ribose and water that weigh as much or more than ...
