Things fit together

I hadn't realised that the A in ATP, adenosine triphosphate, the universal fuel of cellular processes, was the same chemical as the A in the ACGT genetic alphabet. Had you?

Adenine is a purine base. Adenosine is a purine base linked to a ribose molecule. Adenosine triphosphate is adenosine linked to three phosphate groups.

In DNA, the backbone is composed of ribose and phosphate, and the bases stick into the centre of the molecule to bond with each other. IIRC, ATP/GTP/CTP/TTP are the base molecules used in DNA replication. And GTP is sometimes used as an energy source.: )
