Q: Which of the following techniques is commonly used to separate proteins based on their size?

Solution: Gel electrophoresis is a technique used to separate proteins based on their size and charge.

Steps: 8

Step 1: Understand that proteins are molecules made up of amino acids.
Step 2: Know that proteins can vary in size, meaning some are larger and some are smaller.
Step 3: Learn that scientists need a way to separate these proteins to study them.
Step 4: Discover that gel electrophoresis is a method used for this purpose.
Step 5: Realize that in gel electrophoresis, proteins are placed in a gel and an electric current is applied.
Step 6: Understand that the electric current causes the proteins to move through the gel.
Step 7: Know that smaller proteins move faster and further through the gel than larger ones.
Step 8: Conclude that this movement allows scientists to separate proteins based on their size.
