Guida verificata passo dopo passo1
Recall that nucleic acids DNA and RNA are composed of nitrogenous bases that pair specifically to encode genetic information.
List the four nitrogenous bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
List the four nitrogenous bases found in RNA: Adenine (A), Uracil (U), Cytosine (C), and Guanine (G).
Note that RNA contains Uracil (U) instead of Thymine (T), which is present in DNA.
Conclude that the nitrogenous base not present in RNA is Thymine.
