Questions & Step-by-Step Solutions

What is the primary purpose of gel electrophoresis in molecular biology?
  • Step 1: Understand that gel electrophoresis is a laboratory technique.
  • Step 2: Know that it is used to separate molecules like DNA, RNA, or proteins.
  • Step 3: Learn that the separation is based on the size of these molecules.
  • Step 4: Realize that smaller molecules move faster through the gel than larger ones.
  • Step 5: Conclude that the primary purpose of gel electrophoresis is to organize and analyze these molecules by size.
