Guida verificata passo dopo passo1
Recall the principle of complementary base pairing in nucleic acids, where specific nitrogenous bases pair with each other through hydrogen bonds.
Understand that in DNA, cytosine (C) pairs with guanine (G), and adenine (A) pairs with thymine (T).
Recognize that RNA differs from DNA in that thymine (T) is replaced by uracil (U), but the pairing rules for cytosine and guanine remain the same.
Therefore, in RNA, cytosine (C) forms complementary base pairs with guanine (G), just as in DNA.
Summarize that the correct complementary base for cytosine in RNA is guanine (G), not adenine, thymine, or uracil.
