Semi Conservative DNA Replication

The enzyme DNA helicase attaches and moves along the DNA molecule, unwinding the DNA and breaking hydrogen bonds between complementary bases.

Each strands act as a template. new individual DNA nucleotides are attracted to exposed complementary bases on template strand and base pairings occurs (A-T and C-G)

Semi conservative replication ensures that each new DNA molecule contains an original and a new strand and is identical to the original DNA.
