Guanine

|
|
Thymine

|
|
Uracil
|
Detailed explanation-1: -DNA (top) includes thymine (red); in RNA (bottom), thymine is replaced with uracil (yellow).
Detailed explanation-2: -DNA (top) includes thymine (red); in RNA (bottom), thymine is replaced with uracil (yellow). DNA (top) includes thymine (red); in RNA (bottom), thymine is replaced with uracil (yellow).
Detailed explanation-3: -There are two ways for uracil to appear in DNA: thymine replacement and cytosine deamination.
Detailed explanation-4: –Whereas in the RNA, it consists of Ribonucleic acid and phosphate backbone, and nucleotides are similar to that of DNA, except for Thymine wherein the RNA is replaced by the uracil.-Thymine is replaced by the uracil which is complementary to adenine. Hence, the correct answer is option (D).
