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.
The double helix shape of DNA makes DNA replication possible. In replication, DNA makes a copy of itself in order to pass genetic information on to newly formed daughter cells. In order for replication to take place, the DNA must unwind to allow cell replication machinery to copy each strand. Each replicated molecule is composed of a strand from the original DNA molecule and a newly formed strand.
