    8:12 here the 50% that you take as a AT base pairs that are not bp but they are the total no. Of adenine and thymine, for base pairs you have to divide it by 2 as you did in last question

      Let us put this question like this for better understanding, if there are total of 200 bp....It is given as adenine residues 25%. so If A=25%, T =25%, G=25%, C=25%=total 100 %....Adenine and Thymine forms 50% of base pairs...total no of bp is 200, then 50% of 200 is 100...hope you are clear..

      @@biologyexams4u that 100 which you have got is not base pair that is total no. Of adenine and thymine, the question clearly say that 25% is adenine not adenine base pairs
