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

Why does DNA replicate?

• To create another copy for the new cell

• To create a duplicate copy in case the original gets damaged

• To create a new copy to replace the damaged original

DNA replication results in

• 2 completely new DNA molecules

• 2 DNA molecules that each contain a strand of the original

• 1 new DNA molecule and 1 old

• 1 new molecule of DNA

What are the gaps between the newly synthesized DNA on the lagging strand called?

• Okazaki fragments

• Polymer gaps

• Helicase fragments

• Acidic gaps

Which enzyme fixes the Okazaki fragments in the lagging strand?

• Helicase

• Polymerase

• Ligase

• Primerase

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

• continuously

• only in short fragments

• very slowly

• prokaryotically
