1.	Competent cells can be prepared using ________(a) electrophoresis(b) chromatography(c) heat-shock treatment(d) pipettingThis question was addressed to me in semester exam.This question is from Tools of Recombinant DNA Technology: Competent Host topic in division Biotechnology Principles and Processes of Biology – Class 12
Answer» The correct choice is (C) heat-shock treatment Easy explanation: Heat-shock treatment is a method in which the vial is INCUBATED in ice, then treated at temperature up to 50°C and again TRANSFERRED on ice. It is usually used in transferring recombinant DNA within the HOST (bacterial cell).
