Explanation:
DNA replication involves the duplication of the DNA molecule in the NUCLEUS to yield two identical copies. It involves the following steps:
- DNA molecule (double stranded) is unwound or separated into a replication fork by DNA helicase.
- The DNA, which now comprises of two single strands i.e. one strand that runs from the 3'-5' called LEADING STRAND and other strand that runs from '-3' called LAGGING STRAND.
- An enzyme called DNA POLYMERASE attaches to the DNA and adds nucleotide in a bidirectional pattern i.e. adds nucleotide to the leading strand in a 5'-3' direction, then adds short pieces of DNA called OKAZAKI FRAGMENTS to the lagging strand.
- The synthesis of nucleotides by DNA polymerase follows the COMPLEMENTARY BASE PAIRING rule i.e. A-T, G-C.
- Another enzyme called DNA LIGASE joins the okazaki fragments together into a whole DNA.
At the end of replication process, two identical copies of DNA is produced, with each containing one old strand and one new complementary strand.
