Answer:

This composition of nucleotide given in the question do not obey the chargaff"s rule.

Explanation:

According to chargaff"s rule the total number of purine bases will be same to the total number of pyrimidine bases that is

         Adenine+Guanine=Thymine+Cytosine

But here the above quation is not maintained because according to the question A+G=49%

        and T+C = 51%.

Such DNA is replicated by rolling circle model.
