Answer:

1. Ligase  - 5. joins the Okazaki fragments together

(Ligase is involved in joining the okazaki fragments together by sealing the nicks of the DNA strand.

2. Helicase - 1. unwinds the DNA molecule

(Helicase separates the two DNA strands at the replication fork.)

3. Polymerase - 2. synthesizes the complementary daughter strands

(Polymerase synthesizes the complementary daughter strand by adding nucleotides to the DNA.)

4. Topoisomerase - 4. creates nicks ahead of the replication fork to relieve tension from unwinding

(The highly coiled DNA is relaxed by creating nick ahead of the replication fork in the phosphate backbone of DNA strands.)

5. RNA primase - 3. synthesizes RNA primer at the initiation point

(RNA primase synthesizes an RNA primer (short sequence of RNA).)
