DNA Replication

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 picture below shows an enzyme unwinding and unzipping DNA.

​

​What is the name of this enzyme?

• DNA Helicase

• DNA Ligase

• DNA polyermase

• RNA Polymerase

Which enzyme is responsible for adding the free nucleotides to the replicating DNA? ​

• DNA Helicase

• DNA Ligase

• DNA polyermase

• RNA Polymerase

If a person suffered from a disorder where their DNA fragments were unable to fill in the missing slots in between the fragments of the lagging strand, they would most likely have a disorder that affected which enzyme?

• DNA Helicase

• DNA Ligase

• DNA polyermase

• RNA Polymerase

DNA replication runs from ______' to _____' and is said to be ______________________

• 5, 3, antiparallel

• 3, 5, antiparallel

Okazaki fragments appear on which strand of DNA during DNA replication?

• lagging

• leading

If a strand reads:
3' A A A T T T C 5'
The matching strand would read...

• 5' T T T A A A G 3'
• 3' T T T A A A G 5'
• 5' A A A T T T C 3'
• 3' U U U A A A G 5'
