Then, they practice base pairing rules and learn the difference between the bases in an RNA strand an Figure out the color of the different DNA bases. Write a rule for how the bases are arranged/paired in the ladder model of DNA. Calculating Use Chargaff's rules to determine the approximate percentage of thymine in a DNA molecule, if 28% of the nucleotides in the molecule contain adenine. Also known as Chargaff's ratios. Below is a chart of the different bases each organism has. Using Chargaff’s rule, discover which two organisms have the most DNA in common. According to Chargaff’s rule, Concentration of adenine=concentration of thymine.
