  2. Decreases the migration time
  3. Increases the size of the gel
  4. Decreases the temperature of the gel

Questions & Step-by-Step Solutions

What is the effect of increasing the voltage during gel electrophoresis?
  • Step 1: Understand that gel electrophoresis is a technique used to separate molecules, like DNA or proteins, based on their size and charge.
  • Step 2: Know that voltage is the electrical force that pushes the molecules through the gel.
  • Step 3: Realize that when you increase the voltage, you are increasing the force that pushes the molecules.
  • Step 4: Understand that with more force, the molecules can move faster through the gel.
  • Step 5: Conclude that increasing the voltage decreases the time it takes for the samples to migrate through the gel.
