Purines found both in DNA and RNA are:
Cytosine and thymine
Adenine and thymine
Adenine and guanine
Guanine and cytosine
According to the text, nitrogenous bases are of two types: Purines (Adenine and Guanine) and Pyrimidines (Cytosine, Uracil, and Thymine). Adenine and Guanine are the purines found in both DNA and RNA. Among pyrimidines, Cytosine is common to both, while Thymine is present in DNA and Uracil is present in RNA , .
