DNA Replication

DNA replication results in two DNA molecules,

• each one with two original strands
• each one with two new strands
• each one with one new strand and one original strand
• one with two new strands and the other with two original strands

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription

Which enzyme is responsible for adding nucleotides?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

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.

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

Which enzyme fixes the Okazaki fragments in the lagging strand?

• Helicase
• Polymerase
• Ligase
• Primerase

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'

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

• Okazaki fragments
• Polymer gaps
• Helicase fragments
• Acidic gaps

This picture is illustrating the ____ nature of DNA.
