Adenine

from class:

Microbiology

Definition

Adenine is one of the four nitrogenous bases in DNA and RNA, pairing with thymine in DNA and uracil in RNA. It plays a crucial role in encoding genetic information.

congrats on reading the definition of adenine. now let's actually learn it.

ok, let's learn stuff

5 Must Know Facts For Your Next Test

  1. Adenine pairs with thymine via two hydrogen bonds in DNA.
  2. In RNA, adenine pairs with uracil instead of thymine.
  3. Adenine is a purine base, which means it has a double-ring structure.
  4. It is essential for the formation of ATP (adenosine triphosphate), a key energy carrier in cells.
  5. Mutations involving adenine can lead to genetic disorders or diseases.
