DNA Replication Quiz

What is the process of copying DNA called?

• Transcription

• Translation

• Replication

• Mutation

What does each strand of original DNA act as during replication?

• A barrier

• A template

• A catalyst

• A product

What is produced after DNA replication?

• Two different DNA molecules

• Two identical DNA molecules

• One identical and one different DNA molecule

• Three identical DNA molecules

Where does DNA replication take place in eukaryotic cells?

• Cytoplasm

• Nucleus

• Ribosome

• Mitochondria

During which phase of interphase is DNA replicated?

• G1 phase

• G2 phase

• S phase

• M phase

What activities do cells perform during interphase?

• Only cell division

• Only DNA replication

• Cell division, growth, DNA replication, and normal activities

• Only growth

What model does DNA replication follow?

• Conservative model

• Semi-conservative model

• Dispersive model

• Random model

What happens to the two strands of DNA during replication?

• They remain together

• They unwind from one another

• They break into pieces

• They form a triple helix

What does base pairing allow each DNA strand to do during replication?

• Serve as a template for a new complementary strand

• Form a new double helix with itself

• Disintegrate into nucleotides

• Attach to RNA strands

What happens to the hydrogen bonds between bases during DNA replication?

• They strengthen and hold the strands together.

• They break, allowing the helix to unwind into two strands.

• They convert into covalent bonds.

• They form new bonds with proteins.
