What is the role of electrophoresis in the analysis of biological samples?
  1. To separate ions based on their charge and size
  2. To measure the absorbance of light
  3. To quantify the concentration of gases
  4. To determine the boiling point of compounds

Questions & Step-by-Step Solutions

What is the role of electrophoresis in the analysis of biological samples?
  • Step 1: Understand that electrophoresis is a laboratory technique used to separate molecules.
  • Step 2: Know that the molecules being separated can be proteins or nucleic acids (like DNA or RNA).
  • Step 3: Realize that the separation happens because these molecules have different charges and sizes.
  • Step 4: Learn that when an electric current is applied, the charged molecules move through a gel or solution.
  • Step 5: Remember that smaller molecules move faster and farther than larger ones, allowing for separation.
  • Step 6: Conclude that by analyzing the separated molecules, scientists can learn about their properties and functions.
