Detailed explanation-1: -The purine bases are guanine (G) and adenine (A) which form corresponding nucleosides-deoxyribonucleosides (deoxyguanosine and deoxyadenosine) with deoxyribose moiety and ribonucleosides (guanosine, adenosine) with ribose moiety.
Detailed explanation-2: -There are two main types of purine: Adenine and Guanine. Both of these occur in both DNA and RNA.
Detailed explanation-3: -In Fig. 7.4, purines and pyrimidines are shown. Adenine (A) and guanine (G) are purines, and cytosine (C), thymine (T), and urasil (U) are pyrimidines. These are the most important parts in nucleic acid, and genetic information is stored in the sequence of these molecules.
Detailed explanation-4: -Adenine (A) and guanine (G) are purines, and cytosine (C), thymine (T), and uracil (U) are pyrimidines.
Detailed explanation-5: -Purines and Pyrimidines are nitrogenous bases that make up the two different kinds of nucleotide bases in DNA and RNA. The two-carbon nitrogen ring bases (adenine and guanine) are purines, while the one-carbon nitrogen ring bases (thymine and cytosine) are pyrimidines.
