Question

Which type of electrophoresis doesn't take place in a gel, uses high voltage, high speed, and has high resolution?

1) Capillary electrophoresis
2) Gel electrophoresis
3) Agarose electrophoresis
4) Polyacrylamide electrophoresis

Answer 1

Capillary electrophoresis is the technique that uses no gel, employs high voltage and high speed, and achieves high resolution for separating molecules such as DNA, RNA, and proteins.

Step-by-step explanation:

The type of electrophoresis that does not take place in a gel, utilizes high voltage and high speed, and provides high resolution is capillary electrophoresis. Unlike gel electrophoresis, agarose electrophoresis, and polyacrylamide electrophoresis, capillary electrophoresis involves the separation of molecules in a liquid medium within a small capillary tube. This method applies high voltage that facilitates the separation of components based on their size-to-charge ratio with greater efficiency and speed than traditional gel-based methods. The enhanced resolution of capillary electrophoresis allows for the precise separation of very similar molecules, making it valuable in fields such as forensic science, genetic analysis, and pharmaceutical research.
