Guida verificata passo dopo passo1
Recall the four nucleotide bases found in DNA: Adenine (A), Thymine (T), Cytosine (C), and Guanine (G).
Recall the four nucleotide 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 RNA and not present in DNA.
Note that Thymine (T) is present in DNA but replaced by Uracil (U) in RNA.
Conclude that Uracil is the nucleotide base found in RNA but not in DNA.
