Answer:
In dna replication, the strands on the original molecule are used as templates for the synthesis of new dna strands.
Step-by-step explanation:
There isn't much explaining on this one.
but basically just remember that at the end of DNA replication you will end up with 2 DNA molecules, one is the original template DNA strand and the other one is the new DNA strand.
Therefore, they would need an original DNA strand to replicate off of, and that is what we call the template DNA strand.
