검증된 단계별 안내1
Recall the four main nitrogenous bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recall the four main nitrogenous bases found in RNA: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Compare the bases in DNA and RNA to identify which base is unique to DNA and not present in RNA.
Note that Uracil (U) replaces Thymine (T) in RNA, so Uracil is found in RNA but not in DNA.
Conclude that Thymine (T) is the nitrogenous base found in DNA but not in RNA.
