DNA makes copies of itself through the process of replication.  Because the nucleotide bases are complementary, they automatically  make the other strand of complementary ba â¦ ses when the division of  the cell occurs.
Figure 1. Before a cell divides, its DNA is replicated (duplicated.) Because the two strands of a DNA molecule have complementary base pairs, the nucleotide sequence of each strand automatically supplies the information needed to produce its partner.f the two strands of a DNA molecule are separated, each can be used as a pattern or template to produce a complementary strand. Each template and its new complement together then form a new DNA double helix, identical to the original.
