cytosine and uracil
|
Detailed explanation-1: -There are three pyrimidines cytosine, thymine, and uracil and two purines adenine and guanine.
Detailed explanation-2: -Purines (adenine and guanine) are two-carbon nitrogen ring bases while pyrimidines (cytosine and thymine) are one-carbon nitrogen ring bases. Also Read: Amino Acids.
Detailed explanation-3: -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: -Assertion :Purine bases present in DNA are adenine and guanine. Reason: The base thymine is present in RNA while base uracil is present in DNA.
Detailed explanation-5: -Purines that are found in the nucleic acids are Adenine (A) and Guanine (G).
