An Example of Correct Nucleotide Pairing Is

Question

An example of correct nucleotide pairing is
A) T and U.
B) G and U.
C) A and T.
D) C and U.

Accepted Answer

Nucleotide pairing follows a specific pattern where A (adenine) pairs only with T (thymine) and C (cytosine) pairs only with G (guanine). Therefore, the correct nucleotide pairing is A and T, making option C the correct answer. T and U (uracil) pair in RNA, but not in DNA. G and U do not pair together in any nucleic acid. C and U also do not pair together in DNA or RNA.
