DNA Replication

Which sequence of DNA bases would pair with this partial strand
ATG TGA CAG

• ATG TGA CAG
• TAC ACT GTC
• GTA AGT GAC
• CAT TCA CTG

Nitrogenous bases are joined by which type of bond?

• polar bonds
• ionic bonds
• covalent bonds
• hydrogen bonds

The enzyme that unzips 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, 2, 1, 4
• 2, 1, 4, 3
• 2, 3, 1, 4
• 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 ("The Builder")?

• Topoisomerase
• DNA Polymerase
• Ligase
• Primase

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 

The DNA is found in the nucleus of what type of organisms?

• Bacteria
• Eukaryotes
• Prokaryotes
• Viruses

Which enzyme fixes the Okazaki fragments in the lagging strand?

• Helicase
• Polymerase
• Ligase
• Primerase
