Quizplus · Accepted Answer

Thymine is the correct answer because it is one of the four nucleobases in the nucleic acid of DNA that are represented by the letters G–C–A–T. The others are adenine, guanine, and cytosine. Uridine is found in RNA, inosine is a nucleoside that is not a standard base in DNA, and ribose is a sugar component of RNA, not a nucleobase.
