DNA Replication

This enzyme is capable of breaking Hydrogen bonds found between the bases of DNA

• Topoisomerase

• DNA Helicase

• DNA Polymerase

• Exonuclease

What is the purpose of DNA replication?

• Cut the DNA 
• Make more cells
• Apoptosis
• Duplicate the DNA

Which enzyme seals okazaki fragments together on the lagging strand?

• Topoisomerase
• Helicase
• Polymerase
• Ligase

What do we call DNA replication since new DNA has 1 parent strand and 1 new strand?

• Conservative 
• Semiconservative 
• Dispersive

What is the backbone of DNA made of?

• Nitrogen bases
• Amino acids
• Double H
• Sugar & Phosphate

Why is it crucial that living things are able to replicate their DNA?

• Each cell must have its own DNA
• Less copies of DNA are needed when a new cell is created
• A cell needs multiple copies of DNA
• Only muscle cells need DNA 

Which enzyme is responsible for adding nucleotides?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

Each DNA molecule created contain one NEW strand and one OLD strand

• True

• False

Okazaki fragments are found on the _______________ strand

• Leading

• Lagging

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'
