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.
Then after the DNA molecule is in two separate pieces, another molecule called DNA polymerase makes a new strand that matches each of the strands of the split DNA molecule. Each copy of a DNA molecule is made of half of the original (starting) molecule and half of new bases.
