DNA Replication Quiz

What is the role of DNA polymerase in the process of DNA replication?

• It unwinds the DNA helix

• It seals the fragments of DNA together

• It adds nucleotides to the growing DNA strand

• It cuts the DNA strand into smaller pieces

How does DNA replication differ between prokaryotic cells and eukaryotic cells?

• DNA replication in prokaryotic cells involves multiple origins of replication, while eukaryotic cells have only one

• DNA replication in prokaryotic cells is typically bidirectional, while it is unidirectional in eukaryotic cells

• DNA replication in eukaryotic cells involves telomerase, which is not present in prokaryotic cells

• DNA replication in prokaryotic cells occurs in the nucleus, while in eukaryotic cells it occurs in the cytoplasm

What is the structure of DNA commonly referred to as?

• Single strand

• Double helix

• Triple coil

• Quadruple twist

What are the components that form the backbone of the DNA structure?

• Nitrogenous bases

• Amino acids

• Sugar-phosphate

• Carbon rings

What type of bases are found in the DNA structure?

• Oxygenous bases

• Nitrogenous bases

• Carbonous bases

• Phosphorous bases

What is the function of DNA polymerase in DNA replication?

• To break the hydrogen bonds between DNA strands

• To add new nucleotides to the growing DNA strand

• To create the replication fork

• To transport DNA molecules out of the nucleus

What is the replication fork?

• The enzyme that unwinds the DNA helix

• The region where the DNA helix is being separated into two strands

• The new nucleotides being added to the DNA strand

• The direction in which replication occurs

In which direction does DNA replication occur?

• From the replication fork to the DNA polymerase

• From the DNA polymerase to the replication fork

• Away from the replication fork in both directions

• Towards the replication fork in both directions

In the process of DNA replication, what color is used to represent the original DNA strand in the diagram?

• Red

• Blue

• Green

• Yellow

What color represents the new DNA strand in the diagram?

• Orange

• Purple

• Black

• Pink
