DNA Replication Review 2

DNA replication occurs during ​ (a)   .

• interphase
• metaphase
• telophase
• anaphase
• prophase

Reorder the following

• DNA is unzipped

• Primase marks region to begin replication

• Ligase bonds DNA fragments

• Polymerase builds complimentary DNA strand

During replication, what enzyme adds complimentary bases?

• helicase
• synthesase
• ligase
• polymerase

Which of the following is required for DNA replication to occur?

• DNA helicase
• DNA ligase
• DNA polymerase
• all of these

Okazaki fragments form on the:

• lagging strand
• leading strand
• base-pairs
• 5' end

Which of the following must happen first in order for DNA replication to occur?

• DNA polymerase binds to the leading strand
• DNA is unwound
• Hydrogen bonds form between bases
• chromosomes condense

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

• G1
• S
• G2
• M

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

Which of the following is required for DNA replication to occur?

• DNA helicase
• DNA ligase
• DNA polymerase
• all of these

During replication, what enzyme adds complimentary bases?
