The following picture is of _ which separates based on their size and speed.
Correct answer: D. Gel Electrophoresis
- A. Cloning
- B. Recombinant DNA technique
- C. Cell culture
- D. Gel Electrophoresis
Explanation
Gel electrophoresis is a technique used to separate DNA fragments according to their size and speed.DNA samples are loaded into wells (indentations) at one end of a gel, and an electric current is applied to pull them through the gel. DNA fragments are negatively charged, so they move towards the positive electrode.
