MCQ on Chargaff Rule




Chargaff’s rule states that in DNA, the amount of adenine (A) equals thymine (T), and the amount of cytosine (C) equals guanine (G). This principle underlies the complementary base pairing in DNA double helix, crucial for genetic stability and replication. This post on Chargaff Rule Questions will help you to understand this concept of calculating the number of nucleotides in a double stranded DNA.
