State the chargaff rule for DNA base pairing?
According to the chargaff rule for DNA base pairing: All the base pairs, purines(Adenine and Guanine) and pyrimidines(Thymine and Cytosine) paired with each other in 1:1 ratio. Adenine always base paired with Thymine with double hydrogen bonding and Guanine always base paired with Cytosine with triple bonding.
