What is the role of the buffer in gel electrophoresis?

Step 1: Understand that gel electrophoresis is a technique used to separate DNA or proteins.
Step 2: Know that a gel is used to hold the samples and allow them to move.
Step 3: Learn that a buffer solution is added to the gel and the electrophoresis apparatus.
Step 4: Recognize that the buffer helps maintain a stable pH, which is important for the samples to stay intact.
Step 5: Understand that the buffer conducts electricity, which is necessary for the DNA or proteins to move through the gel.
Step 6: Conclude that without the buffer, the samples would not migrate properly, and the results would be inaccurate.
