Questions & Step-by-Step Solutions
Which of the following is a common application of electrophoresis?
Step 1: Understand what electrophoresis is. It is a technique used to separate molecules, like proteins or DNA, based on their size and charge.
Step 2: Know that an electric field is applied during electrophoresis. This electric field causes the molecules to move.
Step 3: Realize that smaller molecules move faster than larger ones when the electric field is applied.
Step 4: Remember that molecules with a positive charge move towards the negative electrode, while those with a negative charge move towards the positive electrode.
Step 5: Conclude that electrophoresis is commonly used in laboratories to separate proteins for analysis.
