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

• 3, 4, 2, 1
• 3, 1, 4, 2
• 2, 1, 4, 3
• 3, 4, 1, 2

In what phase of the cell cycle does DNA replication take place?

• G1
• S
• G2
• M

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

Which of the following does DNA polymerase NOT do?

• connects nucleotides (in the new strand) through covalent bonds
• Matches the template nucleotides with free nucleotides
• proofreads
• It does all of these functions

What does DNA stand for?

• Deoxyribonucleic acid
• Denitrogenous acid
• Deribonucleic acid
• Diribonucleic acid
