Electroporation procedure involves

  • A
    fast passage of food through sieve pores in phloem elements with the help of electric stimulation
  • B
    opening of stomatal pores during night by artificial light
  • Correct answer
    C
    making transient pores in the cell membrane to introduce gene constructs
  • D
    purification of saline water with the help of a membrane system.

Solution

Electroporation is the process used for the transformation of bacteria or plant protoplasts. Electroporation occurs as a result of the reconcentration of lipid molecules of the bilayer membrane to form hydrophilic pores in the membrane. The distribution of such pores, both in terms of size and number, determine the electrical properties of the cell membrane.

Hence, the correct answer is option: 'C'.
