NEET Zoology Biotechnology Principles and Processes Questions Solved


Electroporation facilitates insertion of foreign DNA into the cell by

1. Changing the porocity of the membrane

2. Changing the electrical potential of the membrane

3. Lysing the cell wall

4. Active transport

The membranes are not able to pass electric current and hence act as capacitors. A high voltage current results in their temporary breakdown creating pores big enough through which macromoleclues can pass. Electroporation is 10 times more effective than chemicalmethods.
