Questions and Answers

What is the purpose of nucleic acid electrophoresis?

To separate DNA or RNA fragments by size and reactivity (correct)

To measure the concentration of nucleic acids

To determine the sequence of nucleic acid molecules

To identify the types of nucleic acids present

Why do nucleic acid molecules migrate toward the anode during electrophoresis?

Due to the electric field inducing a random movement

Due to the presence of positively charged ions in the gel

Due to their attraction to the gel medium

Due to their negatively charged sugar-phosphate backbone (correct)

How does the size of a nucleic acid molecule affect its mobility during electrophoresis?

Smaller fragments migrate faster due to less resistance (correct)

Larger fragments migrate faster due to more charge

Smaller fragments migrate slower due to more resistance

Size does not affect mobility in electrophoresis

What happens after the voltage is removed in nucleic acid electrophoresis?
