Gel Electrophoresis – Questions With Solutions (100%
Accurate)
Micropipette Right Ans - Used to suck up small amounts of liquids
DNA is Right Ans - negative and attracts to the positive side of the gel
the difference between smaller and larger DNA fragments Right Ans -
Smaller DNA fragments move quicker and will go farther across the gel
How does gel electrophoresis help identify a criminal Right Ans - everyone
has a unique fingerprint. the suspect with the same DNA bands as the
evidence is the criminal. their DNA was cut in the same places by the
restriction enzymes.
how do you know when the gel box (electrodes) are plugged in and running
Right Ans - You'll see air bubbles
What is true of a DNA fragment closest to the wells Right Ans - they are the
larger fragments because larger DNA moves slower and wouldn't get as far
away
Why do a series of bands appear on the gel Right Ans - Negatively charged
DNA attracts to the positive side, causing tracks of DNA to form on the gel
What would happen if the electrodes were plugged into the wrong outlets?
Right Ans - The DNA would move in the opposite direction. causing it to go
right off the gel.
P-10 Right Ans - 0.5-10 uL
P-20 Right Ans - 2-20 uL
P-50 Right Ans - 5-50 uL
P-200 Right Ans - 20-200 uL
