Where does replication take place?

• in the nucleus of a eukaryotic cell

• in the cytoplasm of a eukaryotic cell

• in the mitochondria of a prokaryotic cell

• in the ribosome of a eukaryotic cell

True or False: Both eukaryotic and prokaryotic cells do DNA replication.

• True

• False

When does the DNA replicate?

• interphase

• prophase

• metaphase

• anaphase

• topoisomerase

This enzyme unzips the strands of DNA

• primase

• helicase

• polymerase

• ligase

• topoisomerase

7. puts the primer on the DNA so that the DNA polymerase knows where to start building a new strand of DNA.

• primase

• helicase

• polymerase

• ligase

• topoisomerase

7. keeps the unzipped stand from over winding

• primase

• helicase

• polymerase

• ligase

• topoisomerase

Which of the following lists the 4 major enzymes important in DNA replication?

• Helicase, DNA polymerase, Ligase, Primase

• Amylase, Lipase, Protease, Helicase

• DNA polymerase, RNA polymerase, Ligase, Primase

• Helicase, Ligase, Amylase, Primase

What bond is being broken in this phase when helicase 'unzips' the strand of DNA?

• hydrogen bond

• covalent bond

• ionic bond

• peptide bond

This uses the old strand of DNA as a set of directions to build the new strand of DNA.

• DNA polymerase

• RNA polymerase

• Helicase

• Ligase

is the glue that holds the DNA strand together.

• Ligase

• Helicase

• Polymerase

• Topoisomerase
