Match statements in column I with results in column II.

Column IColumn II(a)Acceleration of m1 in elevator frame(p)12((m2−m1)g+2m2am1+m2)t2(b)Acceleration of m1 in ground frame(q)12[m2−m1(m1+m2)(g+a)]t2(c)Distance covered of m1 in elevator frame(r)(m2−m1m1+m2)g+(2m2m1+m2)a(d)Distance covered of m1 in ground frame(s)(m2−m1)(m1+m2)(g+a)(t)None of the above

a - s; b - r; c - q; d - p

a - r; b - q; c - p; d - s

a - s; b - t; c - q; d - t

a - r; b - q; c - s; d - p

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.
