It is a process by which DNA makes an identical copy of itself.
HOW DOES IT OCCUR?
DNA REPLICATION TAKES PLACE AS FOLLOWS:
¤Double helix DNA unwind.
¤Weak hydrogen bonds between nitrogeneous bases break.
¤The two DNA strands unzip2/separate.
¤Each original DNA strand serves as a template3 to form a new strand.
¤By attaching to free nucleotides from the nucleoplasm.
¤To form complementary strands4 (A to T and C to G).
¤Each DNA molecule now consists of 1 original strand and 1 new strand.
¤The result is two genetically identical DNA molecules5.
¤The entire process is controlled by enzymes.
