Gel Electrophoresis Virtual Lab
Questions and Answers Rated A+
What is the primary purpose of using a virtual lab for gel electrophoresis?


✔✔A virtual lab allows students to simulate the gel electrophoresis process, helping them

understand the technique without the need for physical materials and minimizing safety risks.




How can you determine the size of DNA fragments after running gel electrophoresis in a virtual

lab?


✔✔By comparing the bands of the sample against a DNA ladder or marker with known sizes,

you can estimate the size of the DNA fragments.




What factors can you manipulate in a virtual lab to observe their effects on gel electrophoresis?


✔✔You can adjust parameters such as gel concentration, voltage, running time, and buffer

composition to see how they influence the separation and resolution of DNA bands.




In a virtual lab, how can you visualize the DNA bands after electrophoresis?


✔✔The simulation may allow for digital staining options where you can visualize the bands

using virtual dyes or by simulating UV exposure.

, Why is buffer choice important in a virtual gel electrophoresis experiment?


✔✔The buffer maintains pH and conductivity, which are crucial for the proper migration of

DNA fragments through the gel matrix.




What might you observe if you set the voltage too high during a virtual gel electrophoresis

experiment?


✔✔Setting the voltage too high can cause excessive heating, leading to band distortion or

smearing, which can affect the accuracy of the results.




How does adjusting the gel concentration affect the outcomes in a virtual gel electrophoresis lab?


✔✔Higher gel concentrations create smaller pores, ideal for resolving smaller DNA fragments,

while lower concentrations allow for better separation of larger fragments.




In the context of a virtual lab, how do you simulate the loading of samples into the gel wells?


✔✔You can drag and drop virtual samples into designated wells, ensuring the correct volume

and avoiding cross-contamination between samples.




What is the significance of including a control sample in your virtual gel electrophoresis

experiment?
