All genetically relevant information of any DNA molecule is present in its sequence of bases on two strands. Therefore the main role of replication is to duplicate the base sequence of parent DNA molecule. The two strands have complementary base pairing. Adenine of one strand pairs with thymine of the opposite strand and guanine pairs with cytosine. This specific complementary base pairing provides the mechartism for the replication.
The two strands uncoil and permanently separate from each other. Each strand functions as a template for the new complementary daughter strand. The base sequence of parent or old strand directs the base sequence of new or daughter strand. If there is adenine in the parent or old strand, complementary thymine will be added to the new strand. Similarly, if there is cytosine in the parent strand, complementary guanine will be copied into the new daughter strand. Maintenance of integrity of genetic information is the main feature of replication.
