DNA Replication Simulation Concepts

The video tutorial guides users through a DNA simulation, starting with setup and control instructions. It covers uncoiling DNA, adjusting simulation speed, and manually replicating DNA by matching base pairs. The tutorial also demonstrates the application of p53 molecules to correct mismatched base pairs, ensuring accurate DNA replication.

What is the dual function of the go/pause button in the simulation?

• It can start or stop the simulation.

• It can save the simulation progress.

• It can reset the simulation.

• It can increase or decrease the simulation speed.

What action is performed by selecting the helicase molecule in the simulation?

• It replicates the DNA.

• It adjusts the simulation speed.

• It coils the DNA.

• It unzips the DNA strand.

How can you increase the speed of the simulation model?

• By clicking the go/pause button.

• By moving the slider to the left.

• By moving the slider to the right.

• By selecting the setup/reset button.

What is the purpose of dragging and dropping complementary base pairs in the simulation?

• To uncoil the DNA.

• To replicate the DNA strand.

• To apply p53 molecules.

• To adjust the simulation speed.

Why might it be helpful to slow down the simulation model during DNA replication?

• To make it easier to grab the correct base pairs.

• To allow more time for the p53 molecules to act.

• To prevent the DNA from unzipping too quickly.

• To increase the accuracy of the helicase molecule.

What is the role of the p53a molecule in the simulation?

• It unzips the DNA strand.

• It increases the simulation speed.

• It replicates the DNA strand.

• It removes mismatched base pairs.

What should you do after a p53 molecule removes a mismatched base pair?

• Apply another p53 molecule.

• Increase the simulation speed.

• Replace it with the correct base pair.

• Restart the simulation.
