Use complete sentences or list form in order to describe the steps of replication. You must use the following words and underline them:

Nucleus Helicase
Complementary strand
DNA Polymerase Ligase
Okasaki Fragments 5’ to 3’ Leading strand
Lagging strand

Please find the description below

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.
