Adenine vs. Adenosine: What's the Difference?

Edited by Sara Rehman || By Sawaira Riaz || Published on December 3, 2023
Adenine is a nitrogenous base in DNA and RNA, while adenosine is a molecule composed of adenine attached to a ribose sugar.

Key Differences

Adenine is one of the four nucleobases in DNA and RNA, playing a crucial role in forming the genetic code. Adenosine, on the other hand, is a nucleoside consisting of adenine and a ribose sugar, serving as a building block for nucleic acids and a participant in energy transfer.
