DNA Replication Quiz

What is the structure of DNA?

• The structure of DNA is a triangle

• The structure of DNA is a double helix.

• The structure of DNA is a square

• The structure of DNA is a single strand

What is the function of DNA in cells?

• DNA helps in maintaining cell shape and structure

• DNA is used for energy production in cells

• DNA carries genetic information and is responsible for the storage, transmission, and expression of genetic information in cells.

• DNA is responsible for producing hormones in cells

Which enzyme is responsible for unwinding the DNA double helix during replication?

• Isomerase

• The enzyme responsible for unwinding the DNA double helix during replication is helicase.

• Ligase

• Polymerase

What is the role of helicase in DNA replication?

• Helicase is responsible for unwinding the double-stranded DNA during replication, creating the replication fork.

• Helicase helps in repairing damaged DNA

• Helicase adds new nucleotides to the DNA strand

• Helicase stabilizes the DNA molecule during replication

Which enzyme is responsible for adding new nucleotides to the growing DNA strand?

• DNA polymerase

• Lipase

• Amylase

• RNA polymerase

What is the function of DNA polymerase III in DNA replication?

• The function of DNA polymerase III in DNA replication is to break down the DNA strand

• The function of DNA polymerase III in DNA replication is to produce RNA molecules

• The function of DNA polymerase III in DNA replication is to repair damaged DNA

• The function of DNA polymerase III in DNA replication is to add nucleotides to the growing DNA strand during the replication process.

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

• DNA polymerase I is responsible for removing the RNA primer and replacing it with DNA nucleotides during DNA replication.

• DNA polymerase I creates the RNA primer for DNA replication

• DNA polymerase I proofreads the DNA sequence during replication

• DNA polymerase I is responsible for unwinding the DNA double helix

Which enzyme is responsible for proofreading and repairing errors in the newly synthesized DNA strand?

• Helicase

• Ligase

• RNA polymerase

• DNA polymerase

What is the function of DNA ligase in DNA replication?

• DNA ligase functions to join the Okazaki fragments on the lagging strand during DNA replication.

• DNA ligase functions to proofread the newly synthesized DNA strands.

• DNA ligase functions to initiate the replication process.

• DNA ligase functions to unwind the DNA double helix during replication.

Describe the process of DNA replication.

• DNA replication is the process of creating two different DNA molecules from a single DNA template

• DNA replication is the process of creating RNA from a DNA template

• DNA replication involves the separation of RNA strands to form a single DNA molecule

• DNA replication is the process by which a double-stranded DNA molecule is copied to produce two identical DNA molecules.
