Question

Which of the following is a pyrimidine base ?​

Answer 1

Answer:

⏩The most important biological substituted pyrimidines are cytosine, thymine, and uracil. Cytosine and thymine are the two major pyrimidine bases in DNA and base pair (see Watson–Crick Pairing) with guanine and adenine (see Purine Bases), respectively. In RNA, uracil replaces thymine and base pairs with adenine.⏪

Answer 2

Three pyrimidine bases, thymine, cytosine, and uracil, and two purine bases, adenine and guanine, are all that are needed to produce the staggering diversity observed in the many species on our planet. Matching one pyrimidine base with one purine base forms a base pair...
