Chapter 9.5, Problem 2COMQ
Summary Introduction
Introduction:
According to Chargaff, the DNA of any organism should possess a 1:1 ratio or equal amounts of pyrimidine and purine bases. Amount of adenine present in the base pair is also equal to the amount of thymine or uracil in RNA and the amount of cytosine is equal to guanine.
