DNA Replication Exit Slip

Reorder the following

• Two identical DNA strands

• DNA is separated by the enzyme DNA helicase

• DNA Polymerase pairs bases to form the new DNA strand

The enzyme that unzips the DNA to prepare for replication

• helicase
• replicase
• polymerase
• synthase

Which enzyme is responsible for adding nucleotides/bases?

• Helicase

• DNA Polymerase

• Ligase

• Primase

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

Why is it crucial that living things are able to replicate their DNA?

• Each cell must have its specific 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

Match the following base pairs.

• Thymine

• Cytosine

• Adenine

• Adenine

• Guanine

• Guanine

• Cytosine

• Thymine

What role do nucleotides play in DNA replication?

• They break down the DNA molecule.

• They act as enzymes to speed up the process.

• They are the building blocks that form the new DNA strands.

• They transport DNA molecules out of the nucleus.

Replication is called semi-conservative because

• Each new molecule contains part of the original DNA

• sometimes it conserves fuel

• DNA conserves ecosystems
