DNA Replication Honors Biology

Which enzyme is responsible for adding nucleotides to the new strands during DNA replication?

• Topoisomerase

• DNA Polymerase

• Ligase

• Helicase

Which sequence of DNA bases would pair with this partial strand

ATG TGA CAG

• ATG TGA CAG

• TAC ACT GTC

• TAC AGT GAC

• CAT TCA CTG

A process in which DNA has the unique ability to make an exact copy of itself.

• Replication
• Translation
• Transcription

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

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

• G1
• S
• G2
• M

Which enzyme breaks the hydrogen bonds between the two DNA strands in order to separate them in order to start replication?

• Topoisomerase

• Helicase

• DNA polymerase

• Ligase

What do we call DNA replication since new DNA has 1 parent strand and 1 new strand?

• Conservative

• Semiconservative

• Libertarian

• Liberal

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

• Each cell must have its own copy of the organism's DNA

• Less copies of DNA are needed when a new cell is created

• A cell needs many copies of each strand of DNA

• Only muscle cells need DNA
