In E.Coli DNA, the AT/GC ratio is 0-93. If the number of moles of adenine in the DNA sample is 465,000, calculate the number of moles of guanine present.

Answer»

Solution :Since the number of MOLES of adenine MUST be equal to that of thymine, therefore ,
`(A+T)=465,000+465,000=930,000`.
Since `(A+T)//(C+G)=0.93`,
therefore, number of moles of `C+G=(930,000)/(0.93)=10,00,000`
Further since the number of moles of C=number of MOLECULE of G.
`therefore` No. of moles of GUANINE (G)`=1000,000//2=500,000`.
