Which nitrogenous bases are purines?
The nitrogenous bases adenine (A) and guanine (G) are classified as purines
The nitrogenous bases adenine (A) and guanine (G) are classified as purines. Purines have a double-ring structure, consisting of a six-membered ring fused to a five-membered ring. Adenine has a six-membered ring fused to a five-membered ring, and guanine has two six-membered rings fused together. These purine bases are important components of nucleotides, which are the building blocks of DNA and RNA molecules. They play a crucial role in the genetic code as they form base pairs with the pyrimidine bases (thymine, cytosine, and uracil) to stabilize the DNA double helix structure. Additionally, purines have significant roles in various biological processes, such as energy metabolism and signal transduction.
