During DNA Replication, the DNA gets unwound by which enzyme?

• Primase

• Helicase

• DNA Polymerase

• DNA Ligase

How does helicase create the replication fork (ie. separate the strands of DNA).

• By using a primer

• By using DNA polymerase

• By breaking the hydrogen bonds between base pairs

• By sealing the hydrogen bonds between base pairs

The leading strand runs in which direction?

• 3' --> 5'

• 5' --> 3'

The lagging strand runs in which direction?

• 5' --> 3'

• 3' --> 5'

What is added to the leading strand that indicates were DNA synthesis can begin?

• Primase

• Helicase

• DNA Polymerase

• Ligase

On the lagging strand, a primer is added, which enzyme binds here to begin DNA replication?

• Ligase

• Helicase

• DNA Polymerase

• RNA Polymerase

The lagging strand contains multiple primase sections, this results in discontinuous DNA segments to be added, what are these called?

• Okazaki fragments

• RNA Primer

• DNA Primer

• Annealing

During DNA replication, when the base pairs are matched, the primers have to be removed by which enzyme?

• Helicase

• Exonuclease

• Ligase

• Primase

During DNA replication the new strand must be proof read, which enzyme does the proofreading?

• RNA Polymerase

• Ligase

• Helicase

• DNA Polymerase

The human genome is contained in which two compartments?

• Nucleus, Ribosomes

• Nucleus, Mitochondria

• Ribosomes, Mitochondria

• Mitochondria, Golgi Body
