AP Biology Replication

The enzyme that unzips the DNA to prepare for replication

• helicase

• replicase

• polymerase

• synthase

In what phase of the cell cycle does DNA replication take place?

• G1

• S

• G2

• M

The process of DNA replication is called semi conservative because it results in

• none of these

• Two DNA molecules.  One original molecule and one with two new strands

• two exact copies with new strands

• two identical molecules, each with 1 original strand and one new.

Which enzyme seals okazaki fragments together on the lagging strand?

• Topoisomerase

• Helicase

• Polymerase

• Ligase

• F

• G

• H

• J

What process is shown in the image?

• Transcription

• Translation

• DNA Replication

• DNA Transformation

Polymerase is able to replicate the new DNA ______ along the leading strand.

• continuously

• only in short fragments

• very slowly

• prokaryotically

The picture below shows the steps of DNA replication beginning with step one and ending with step three.

​Because you are reusing the old, or parent, DNA strand DNA replication is said to be

• Semi- Conservative

• Semi-discontinuous

• Continuous

• Fully-Conserveative

The goal of DNA replication is

• to make proteins in the cell

• to divide cells

• to make an identical copy of DNA

• to fix mistakes in the DNA

Arrange the step in DNA replication in order

• replication fork formation or unzipping

• 3

• termination

• 1

• elongation

• 2

• primer binding

• 4
