Question

genetic code quiz complete 1 2 3 according to chargaffs rule, base pairing in dna should resemble which of the following? a = t; c = g a = c; t = g a = g; t = u a = u; c = g

Explanation:

Chargaff's rule states that in DNA, the amount of adenine (A) is equal to thymine (T), and the amount of cytosine (C) is equal to guanine (G). This is because of the complementary base - pairing in DNA. Uracil (U) is found in RNA, not DNA. So, we check each option for correct base - pair equality and presence of DNA bases.

Answer:

A. \(A = T; C = G\)
