What is the purpose of the wells at the top of the gel? 
The wells are used to load DNA samples into the gel before the electrophoresis process 
begins. 
 
Why are the DNA samples loaded near the negative end of the gel? 
DNA is negatively charged, so it is loaded near the negative end so it can migrate toward the 
positive end. 
 
What do the bands on the gel represent? 
The bands represent DNA fragments that have been separated based on...

PCR and Gel Electrophoresis Questions 
 
and Answers Graded A+ 
 
What’s the primary purpose of PCR before running a gel electrophoresis? 
PCR amplifies specific DNA segments, making millions of copies so that there’s enough to 
see when you run it through the gel. 
 
How does PCR know which part of the DNA to copy? 
PCR uses primers—short sequences that match the start and end of the target DNA region, 
telling the enzyme exactly where to begin and stop copying.

Gel Electrophoresis Questions and 
 
Answers Already Passed 
 
What is gel electrophoresis primarily used for in molecular biology? 
 Gel electrophoresis is primarily used for separating nucleic acids or proteins based on their 
size and charge. 
 
How does gel electrophoresis work to separate DNA fragments? 
 Gel electrophoresis works by applying an electric field to a gel matrix, causing negatively 
charged DNA fragments to migrate towards the positive electrode, with smaller fragments 
moving...

Answers Rated A+ 
 
What role does gel electrophoresis play in gene therapy research? 
Gel electrophoresis is used to analyze the delivery and integration of therapeutic genes into 
target cells, helping assess the effectiveness of gene therapy approaches. 
 
How can gel electrophoresis help identify pathogens in a clinical setting? 
By amplifying specific genetic markers of pathogens and separating them using gel 
electrophoresis, researchers can quickly ide...

Lab 3 Gel Electrophoresis Questions 
 
and Answers Graded A+ 
 
What would happen if you dropped your DNA sample outside the well? 
If you miss the well, your sample would float away in the buffer, and nothing will separate 
during the run! 
 
Why does DNA naturally "run away" from the negative end of the gel? 
DNA has a negative charge due to its phosphate backbone, so it’s repelled by the negative 
electrode and races toward the positive side. 
 
What do the DNA bands look like under U...

What is the role of the agarose gel in gel electrophoresis? 
The agarose gel provides a medium through which the DNA or protein fragments can 
migrate, allowing for separation based on size. 
 
How does the electric field affect the movement of DNA in gel electrophoresis? 
The electric field causes negatively charged DNA molecules to move towards the positive 
electrode, facilitating their separation.

Questions (Quiz SG) Already Graded A 
 
What makes DNA think it’s in a race during gel electrophoresis? 
The electric current applied to the gel gives DNA a nudge, and since DNA is negatively 
charged, it dashes toward the positive side like it’s racing to the finish line! 
 
Why do the smaller DNA fragments win the "gel race"? 
Smaller fragments are like speedy sprinters—they easily slip through the tiny spaces in the 
gel, leaving the larger fragment...

Gel electrophoresis Questions and 
 
Answers Graded A+ 
 
What kind of "track" does gel electrophoresis create for DNA? 
It creates a microscopic race track where DNA fragments can compete based on size, with 
smaller fragments sprinting ahead! 
 
If DNA fragments were athletes, how would they compete in gel electrophoresis? 
Smaller athletes (fragments) would zoom through the gel like sprinters, while larger ones 
lumber along, taking their sweet time.
