Gel Electrophoresis
Gel Electrophoresis
A technique used to separate and analyze biological molecules based on their size and charge.
Why are lipids not used in gel electrophoresis?
Why are lipids not used in gel electrophoresis?
Lipids, such as fats and oils, are not easily separated by gel electrophoresis because they are not charged and don't dissolve well in water.
What does the gel matrix do in gel electrophoresis?
What does the gel matrix do in gel electrophoresis?
The gel matrix acts as a sieve, slowing down larger molecules and allowing smaller molecules to move through more easily.

Study Notes
Gel Electrophoresis
- Lipids are NOT a biological molecule that can be separated and analyzed using gel electrophoresis.
- The gel matrix serves as a scaffold to separate and analyze biological molecules based on their size and charge.
- Gel electrophoresis does NOT play a crucial role in ecology.
- Gel electrophoresis relies on the principle that biological molecules with different sizes and charges will migrate at different speeds in an electric field.
- Agarose or polyacrylamide are commonly used to create the gel matrix in gel electrophoresis.
- DNA, RNA, and proteins can be separated and analyzed using gel electrophoresis.
- The gel matrix acts as a sieve, allowing smaller molecules to migrate faster than larger ones.
- The migration speed of molecules in gel electrophoresis is determined by their size and charge.
- Gel electrophoresis is important in molecular biology, genetics, and biochemistry, but NOT in ecology.
