Explanation:
Detailed explanation-1: -Thus, thymine is the nitrogenous base which is not present in RNA.
Detailed explanation-2: -Adenine (A), guanine (G), cytosine (C), and thymine (T) are the four bases found in DNA. Adenine (A), cytosine (C), uracil (U), and guanine (G) are the four bases found in RNA. The nitrogenous base uracil is absent from DNA. Uracil is a pyrimidine present in RNA that has the similar structure as thymine in DNA.
Detailed explanation-3: -In RNA, however, a base called uracil (U) replaces thymine (T) as the complementary nucleotide to adenine (Figure 3).
