Detailed explanation-1: -Properties. Guanine, along with adenine and cytosine, is present in both DNA and RNA, whereas thymine is usually seen only in DNA, and uracil only in RNA.
Detailed explanation-2: -Adenine and guanine are found in RNA and DNA in terrestrial life, whereas thymine is only found in DNA and uracil only in RNA.
Detailed explanation-3: -Final answer: Purines found both in DNA and RNA are adenine and guanine.
Detailed explanation-4: -Guanine is a purine nucleobase with a chemical formula of C5H5N5O. Purines are heterocyclic aromatic organic compounds. As a purine, adenine is comprised of two carbon rings: a pyrimidine ring and an imidazole ring. Guanine occurs in both DNA and RNA.
Detailed explanation-5: -DNA base pair. Under normal circumstances, the nitrogen-containing bases adenine (A) and thymine (T) pair together, and cytosine (C) and guanine (G) pair together. The binding of these base pairs forms the structure of DNA .
