Provide a summary of what happens during DNA replication using the following words: Helicase, DNA polymerase, Primase, Ligase, Parent strand, new strand, nucleotides, and semi-conservative model.

Please find the summary of what happens during DNA replication below

Explanation:

DNA replication is the process by which a DNA molecule is duplicated into two identical copies. It occurs in the nucleus of the cell prior to any cellular division. The process includes:

- The double stranded DNA is first unwound by an enzyme called DNA HELICASE into a replication fork consisting of two single strands of DNA.

- Another enzyme called DNA POLYMERASE binds to the DNA and begins to add NUCLEOTIDES to each strand using complementary base pairing rule i.e. A-T, G-C. To do this, short sequences of RNA called PRIMER are synthesized by an enzyme called PRIMASE, which serves as building block for DNA polymerase to act.

- However, DNA POLYMERASE can only work in the 5'-3' direction i.e. on the leading strand which runs from 3'-5' direction. Short pieces of DNA called OKAZAKI fragments are synthesized on the lagging strand, which runs from 5'-3' direction.

- An enzyme called LIGASE joins the okazaki fragments together into a whole DNA on the lagging strand.

After the replication process which follows the SEMI-CONSERVATIVE MODEL of replication, each DNA molecule will contain one old strand called PARENT STRAND and one NEW strand.

it's not c. i took the quiz and got it wrong. so my best guess is b.

have a great day, and hope this .
