Adenine and guanine

HOPE THIS HELPS YOU..

Answer 2

Purines found both in DNA and RNA are Adenine and guanine

Step by step explanation:

• Purines are one of two groups of molecules that comprise nitrogen, or nitrogen bases.

• All purines have a double-ringed structure consisting of a six-membered ring fused into a 5-membered ring;

• The purine ring is a heterocyclic molecule.

• Each of the rings of a purine comprises two nitrogen atoms within the double-ringed form, for a total of four.
• Such atoms of nitrogen are found in all purines in the same places.
• Purines are Adenine and Guanine which are present in both DNA and RNA.
