Vedclass · Answer

(D) The correct answer is $D$. Gel electrophoresis is a technique used to separate $DNA$ fragments based on their size and charge. While the question asks for isolation,in the context of standard biotechnology curriculum,gel electrophoresis is the primary method used to isolate and purify specific $DNA$ fragments from a mixture after they have been extracted and digested with restriction enzymes. Other options like 'Selectable marker' are used for identifying transformants,'Micro-injection' is a method for direct gene transfer,and 'Biolistic' (gene gun) is a method for introducing $DNA$ into cells.

Which of the following methods is used for the isolation of $DNA$?
