Guanine is a component of several important biomolecules involved in energy metabolism, such as guanosine triphosphate (GTP ... is understanding the complex interplay between guanine and the other ...

This image illustrates the chemical structure of a purine molecule ... It pairs with cytosine (C) through three hydrogen bonds, providing stability to the DNA double helix. Guanine is also a component ...

But James Watson and Francis Crick's claim was a valid one, for they had in fact discovered the structure of DNA, the chemical that encodes instructions for building and replicating almost all ...

This way DNA can reproduce itself without changing its structure -- except for occasional errors, or mutations. The structure so perfectly fit the experimental data that it was almost immediately ...
