help 9-12 please

9 PCNA is a a. Eukaryotic sliding clamp b. Prokaryotic SSB C. Eukaryotic proof reader d. Eukaryotic 3-5' Exonuclease 10. One of the following is false a. Okazaki fragments are short fragments synthesized semidisconti b. Okazaki fragments are shorter in size in prokaryotes but longer in eukaryotes c. Okazaki fragments have RNA as primer synthesized by primase d. None of the above nuously 11. Nick translation ability is present in a. DNA Pol I b. DNA Pol II c. DNA Pol III d. DNA Pol IV 12 The enzyme that unwinds a segment of the DNA molecule is... a. DNA polymerase

Explanation / Answer

9)

PCNA is a homotrimer eukaryotic part of beta ali ding camp kahich confers the high processivity of pol deta and epsilon.

Hence option (a) is correct.

10) Eukaryotic okazaki fragments are smaller than prokaryotic okazaki fragments. These fragments can be synthesized semidiscontinuosly and RNA primer is synthesized by enzyme prima se.

Hence option (b) is false statement.

11)Nick translation ability the one way to make labeled probes .DNA Polymerase I is I removes the leading bases at the Nick 5'----->3'direction.

Hence option (a) is correct.

12)

DNA helicase is used to unwind the DNA stand which separates to both stand and form a replication fork.

Hence DNA helicase is correct option.
