Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

According to Chargaff's rule, for a double stranded DNA, the ratios between adenine and thymine and guanine and cytosine are constant and equals one (A+G = C+T). It also states that in natural DNA, the base ratio A/T is close to unity and C/G is also close to unity. Whereas, the A+T/G+C ratio is species specific and it is constant for a particular species and varies between the species.
