What is gel electrophoresis?
Understand the Problem
The question appears to be asking for information about gel electrophoresis, a laboratory technique used to separate mixtures of DNA, RNA, or proteins according to their size and charge. It involves the movement of charged particles through a gel under the influence of an electric field, which allows for analysis and purification of biomolecules.
Answer
Gel electrophoresis separates DNA, RNA, or proteins by size and charge.
Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to their size and charge.
Answer for screen readers
Gel electrophoresis is a laboratory method used to separate mixtures of DNA, RNA, or proteins according to their size and charge.
More Information
Gel electrophoresis involves applying an electric field to move charged molecules through a gel matrix. Smaller molecules move faster, allowing them to be separated by size. This method is essential in molecular biology for analyzing DNA, RNA, and protein samples.
Tips
A common mistake is misunderstanding which direction molecules will migrate; remember that DNA and RNA are negatively charged and move towards the positive electrode.
