Answer 2

For strand separation and stabilization during DNA replication, the set of enzymes and proteins required are topoisomerase, helicase, and SSBP.

• DNA replicates by the semi-conservative method. A new complementary strand forms for each DNA strand.
• The steps involved in replication are the Unwinding of DNA, elongation, and ligation of the DNA.
• The DNA unwinds by the topoisomerase.
• And supercoiling of DNA is prevented by the helicase enzyme is used.
• The single-stranded DNA is unstable, so SSBP (Single-Stranded Binding Protein) gets attached to the DNA strand to make it stable.
• After this, DNA polymerase uses in the elongation step.
• And the DNA fragments are joined by the DNA ligase enzyme.
• Hence, the correct answer is an option (4).
