Exploring DNA Replication: Enzymes in Prokaryotes and Eukaryotes

What is the term used to describe the replication process where each new DNA molecule contains one parent strand and one daughter strand?

• Conservative

• Semi-conservative

• Dispersive

• Non-conservative

Which enzyme in prokaryotes is responsible for unwinding the DNA strands at the origin of replication?

• DNA B protein

• DNA A protein

• DNA C protein

• DNA G protein

What is the role of DNA C protein in prokaryotic DNA replication?

• It removes RNA primers.

• It joins DNA segments together.

• It acts as a loading factor for DNA B helicase.

• It synthesizes short RNA primers.

Which enzyme in prokaryotes is responsible for relieving stress on DNA strands during replication?

• DNA helicase

• DNA gyrase

• DNA polymerase I

• DNA ligase

What is the primary function of DNA polymerase III in prokaryotes?

• Removing RNA primers

• Mediating the DNA replication process

• Replication of mitochondrial DNA

• DNA repair

What is the role of the origin recognition complex (ORC) in eukaryotic DNA replication?

• It synthesizes RNA primers.

• It recognizes and binds to the origin of replication.

• It unwinds the DNA strands.

• It joins DNA segments together.

Which protein ensures that DNA is replicated only once during the cell cycle in eukaryotes?

• PCNA protein

• MCM protein

• CDT1 protein

• CDC6 protein

What is the function of PCNA protein in eukaryotic DNA replication?

• It acts as a DNA clamp to ensure processivity of DNA polymerase.

• It unwinds the DNA strands.

• It synthesizes RNA primers.

• It removes RNA primers.

Which DNA polymerase in eukaryotes is primarily responsible for synthesizing both leading and lagging strands?

• DNA polymerase delta

• DNA polymerase gamma

• DNA polymerase beta

• DNA polymerase alpha

Which DNA polymerase in eukaryotes is involved in the replication and repair of mitochondrial DNA?

• DNA polymerase beta

• DNA polymerase alpha

• DNA polymerase gamma

• DNA polymerase delta
