Answer:
make an exact copy of a DNA strand for bacterial reproduction
Explanation:
The purpose of DNA replication would be to make an exact copy of a DNA strand for bacterial reproduction.
DNA replication is a process during which an extra copy of an organism's DNA is made following a series of steps. The replication usually precedes reproduction or the formation of daughter cells. Each daughter cells resulting from reproduction must have a complete genome that mirrors that of the parent or otherwise depending on the type of reproduction.
Without reproduction, DNA replication would not have been necessary.
