Detailed explanation-1: -There are two main types of purine: Adenine and Guanine. Both of these occur in both DNA and RNA.
Detailed explanation-2: -Purines. Adenine and guanine are found in both DNA and RNA.
Detailed explanation-3: -Nitrogenous bases present in the DNA can be grouped into two categories: purines (Adenine (A) and Guanine (G)), and pyrimidine (Cytosine (C) and Thymine (T)).
Detailed explanation-4: -The most important biological substituted purines are adenine and guanine, which are the major purine bases found in RNA and DNA. In DNA, guanine and adenine base pair (see Watson-Crick pairing) with cytosine and thymine (see pyrimidines) respectively.
Detailed explanation-5: -DNA and RNA both have four bases; two purines and two pyrimidines, in the nucleotide chains. The purines adenine and guanine and the pyrimidine cytosine are common to both DNA and RNA.
