Electroporation is making transient pores in cell membranes to introduce gene constructs purification of saline water with the help of membrane system opening of stomata by artificial light during night fast passage of nutrients through phloem sieve pores by electric stimulation

Answer: Making transient pores in the cell membrane to introduce gene constructs.

Explanation:

Electropermeabilization is another term for electroporation. It is a method that uses an electrical field to improve the permeability of the cell membrane, allowing DNA to enter the cell. Electroporation is a technique used in molecular biology to convert bacteria, yeast, or plant protoplasts. Electroporation is also an effective method for introducing foreign genes into tissue culture cells.

Consider the following statements: A. The electric potential due to a dipole at its axial point is zero. B. The electric potential due to a dipole at its equatorial point is zero. C. The electric potential due to a dipole at its axial point is non-zero. D. The electric potential due to a dipole at its equatorial point is non-zero. B and D are true B and C are true A and B are true A and D are true

During the kinetic study of the reaction, 2A+B→C+D, following results were obtained: Rate=k[A]2[B] Rate=k[A][B] Rate=k[A]2[B]2 Rate=k[A][B]2

Answer:

Rate law is written as rate =K[A]2[B]

Explanation:

  • The rate law is written in terms of two reactants A and B.
  • The overall reaction order is three(2+1).
  • The reaction order is two with respect to A.
  • The reaction order is one with respect to B.

During a thunderstorm, it is not safe to use mobile phones and cordless phones. True False
