1.29 DNA Replication

Based on the diagram, the enzyme (represented in gray) is most likely...

• DNA polymerase

• DNA Ligase

• Nuclease

• Helicase

After DNA is unzipped, which enzyme is responsible for base pairing the nucleotides to make a copy (complementary strand) of the DNA?

• helicase

• DNA polymerase

The picture below shows the steps of DNA replication beginning with step one and ending with step three.

​Because you are reusing the old, or parent, DNA strand DNA replication is said to be

• Semi- Conservative

• Semi-discontinuous

• Continuous

• Fully-Conserveative

During DNA replication, which enzyme is responsible for unwinding the double helix?

• DNA polymerase

• DNA ligase

• DNA helicase

• Topoisomerase

Why is DNA replication essential for the growth and repair of organisms?

• It creates new cells

• It repairs damaged DNA

• It provides energy

• It synthesizes proteins.
