Detailed explanation-1: -RNA contains cytosine and uracil as pyrimidine bases while DNA has cytosine and thymine as pyrimidine bases. Both RNA and DNA have the same purine bases i. e., guanine and adenine.
Detailed explanation-2: -Cytosine can be found as part of DNA, as part of RNA, or as a part of a nucleotide. As cytidine triphosphate (CTP), it can act as a co-factor to enzymes, and can transfer a phosphate to convert adenosine diphosphate (ADP) to adenosine triphosphate (ATP). In DNA and RNA, cytosine is paired with guanine.
Detailed explanation-3: -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.
Detailed explanation-4: -c) Cytosine: It is present in both DNA and RNA. It is a pyrimidine and pairs with guanine (purine) by a triple hydrogen bond.
Detailed explanation-5: -Purines. Adenine and guanine are found in both DNA and RNA.
