Detailed explanation-1: -In DNA, Adenine, Guanine, Cytosine, and Thymine are observed. Whereas in RNA, Adenine, Guanine, Cytosine, and Uracil are observed. In RNA, Thymine is replaced by Uracil. Hence, Adenine, Guanine, and Cytosine are common to both DNA and RNA.
Detailed explanation-2: -The bases used in DNA are adenine (A), cytosine (C), guanine (G) and thymine (T). In RNA, the base uracil (U) takes the place of thymine. DNA and RNA molecules are polymers made up of long chains of nucleotides.
Detailed explanation-3: -Because thymine has a higher resistance to photochemical mutation and makes the genetic code more durable, DNA uses it instead of uracil. This is required to store all the data required for life to function. The chemical breakdown of cytosine results in the easy production of uracil in DNA.
Detailed explanation-4: -Thiamine and Uracil are pyrimidines found in DNA & RNA respectively.
