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.
Every step of DNA replication needs special molecules to do the work. These molecules are called enzymes. As we go through this, remember, all that is happening is the DNA is being unzipped and each side of the zipper is being copied.
