Question

Name the specific enzyme responsible for nucleotide polymerisation in DNA replication. Write two characteristic features of this enzyme. Name the region on E. coli DNA where this enzyme can initiate replication.

Answer 1

Answer:

Enzymes involved in DNA replication are:

• Helicase (unwinds the DNA double helix)
• Gyrase (relieves the buildup of torque during unwinding)
• Primase (lays down RNA primers)
• DNA polymerase III (main DNA synthesis enzyme)
• DNA polymerase I (replaces RNA primers with DNA)
• Ligase (fills in the gaps)

Answer 2

Answer:

Enzymes involved in DNA replication are:

Helicase (unwinds the DNA double helix)

Gyrase (relieves the buildup of torque during unwinding)

Primase (lays down RNA primers)

DNA polymerase III (main DNA synthesis enzyme)

DNA polymerase I (replaces RNA primers with DNA)

Ligase (fills in the gaps)
