Guida verificata passo dopo passo1
Understand that nucleic acids DNA and RNA are composed of nitrogenous bases paired with a sugar-phosphate backbone.
Recall that DNA contains the bases adenine (A), thymine (T), cytosine (C), and guanine (G).
Recall that RNA contains adenine (A), uracil (U), cytosine (C), and guanine (G), but not thymine.
Recognize that uracil replaces thymine in RNA, so thymine is the nitrogenous base not found in RNA.
Therefore, the nitrogenous base absent in RNA is thymine.
