Fragments of DNA formed after treatment with endonucleases are separated by the technique of _______

Fragments of DNA formed after treatment with endonucleases are separated by the technique of _______ Correct Answer gel electrophoresis

DNA is a charged molecule. When fragmented, it can be separated by the technique called gel electrophoresis. It is a technique in which the molecules are separated based on the charge present on that molecule.
