adeninë

Adenine is a nucleobase found in DNA and RNA, playing a crucial role in the genetic code of living organisms. It is one of the five nucleobases in DNA, along with thymine, cytosine, guanine, and uracil in RNA. Adenine is a purine, a type of nucleobase characterized by a six-membered ring fused to a six-membered ring. In DNA, adenine pairs with thymine through two hydrogen bonds, while in RNA, it pairs with uracil. Adenine is also a component of adenosine triphosphate (ATP), the primary energy currency of cells. It is synthesized through the de novo pathway or salvaged from the diet. Adenine is essential for various biological processes, including DNA replication, transcription, and translation. Its structure and properties make it a vital component of the genetic material and energy metabolism in all living organisms.
