About BCM 311 at Benson Idahosa University

BCM 311 is a 300 Level course at Benson Idahosa University. Students preparing for BCM 311 exams on Testwiz get 257+ practice questions across 27 topics, including theory questions and topic summaries.

Instead of cramming the night before, students who practice by topic — Function of DNA Gyrase and SSB Proteins, Postreplicative Mismatch Repair in E. coli, Primase and RNA Primer Synthesis, and more — build real familiarity with how Benson Idahosa University tests BCM 311, catch weak spots early with Testwiz's analytics, and walk into the exam with actual reps under their belt.

Sample questions

1. Which of the following BEST describes the primary function of DNA gyrase during DNA replication in E. coli?

a.It loads the DnaB helicase onto the origin of replication.

b.It synthesizes RNA primers to initiate DNA synthesis.

c.It binds to single-stranded DNA to prevent reannealing.

d.It relieves topological stress by introducing negative supercoils.

2. In postreplicative mismatch repair in E. coli, the repair system distinguishes the newly synthesized strand from the parent strand based on:

a.the presence of nicks introduced by DNA gyrase.

b.the presence of RNA primers on the new strand.

c.the methylation status of adenine in GATC sequences.

d.the binding of single-stranded binding proteins.

3. The RNA primer synthesized by primase during E. coli replication is typically how long?

a.100–200 nucleotides

b.4–6 nucleotides

c.20–30 nucleotides

d.10±1 nucleotides

4. Which of the following is NOT a function of the 3' to 5' exonuclease activity of DNA polymerase?

a.Excising RNA primers during lagging strand maturation.

b.Hydrolyzing phosphodiester bonds to remove the last added nucleotide.

c.Removing incorrectly incorporated nucleotides during proofreading.

d.Increasing the fidelity of DNA replication by correcting errors.

5. What is the role of DnaC in the initiation of DNA replication in E. coli?

a.It synthesizes the RNA primer required for DNA polymerase.

b.It relieves supercoiling generated by the unwinding of DNA.

c.It acts as a helicase loader, forming a complex with DnaB.

d.It binds to the origin and bends the DNA to facilitate unwinding.
