.The process by which DNA is copied in a cell before a cell divides by mitosis, meiosis, or binary fission.

1. enzymes called helicases separate the DNA strands

Replication fork: The Y-shape d region that results when th e two strands seperate


2. enzymes called DNA polymerases add complementary nucleotide, found floating freely inside the nucleus, to each of the original strands

3.DNA polymerases finish replicating the DNA and fall off

Semi-conservative replication
: each of the new DNA molecules has kept one of the two original DNA strands.

Which have circular chromosome.
Replication starts at one place and stops when each end point meets.
