Which sequence of DNA bases would pair with this partial strand
CAT TCA CTG

• ATG TGA CAG
• TAC ACT GTC

Which of the following units are repeatedly joined together to form a strand of DNA?

• amino acids
• nucleotides
• fatty acids
• polysaccharides

The enzyme that unwinds the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

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

order of replication

Which enzyme is responsible for adding nucleotides?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

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

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'

This picture is illustrating the ____ nature of DNA.

• anti-parallel
• deoxyribosic
