DNA Replication

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

• Replication

• Translation

• Transcription

Which sequence of DNA bases would pair with this partial strand CAT TCA CTG

• ATG TGA CAG

• TAC ACT GTC

• GTA AGT GAC

• CAT TCA CTG

The picture below shows an enzyme unwinding and unzipping DNA.

​​What is the name of this enzyme?

• 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?

• Anaphase

• Interphase

• Prophase

• Metaphase

Which enzyme is responsible for adding nucleotides?

• RNA Polymerase

• DNA Polymerase

• Ligase

• Primase

The process of DNA replication is called semi conservative because it results in

• Two DNA molecules. One original molecule and one with two new strands

• two exact copies with new strands

• two identical molecules, each with 1 original strand and one new

• none of these

Identifies the starting point for DNA polymerase to start building the new DNA molecule

• DNA Polymerase

• ligase

• helicase

• primase

Direction new nucleotides are synthesized on the new strand

• 5' to 3' (new nucleotides added to the 3' end)

• 3' to 5' (new nucleotides added to the 5' end)

• 3' to 5' (new nucleotides added to the 3' end)

• 5' to 3' (new nucleotides added to the 5' end)

Direction DNA is read

• 5' to 3'

• 3' to 5'
