"WebThis is the first step in the process of DNA replication. After the strands are split apart, RNA primers are added to the template strands. These primers give the DNA polymerase enzymes a place to start making new strands of DNA. The DNA polymerase enzymes then start making copies of the original DNA strands that are the same but not the same. " - First step in process of dna replication
