Significance of the ‘heat shock’ method in bacterial transformation is to facilitate:

Options

  1. ABinding of DNA to the cell wall
  2. BUptake of DNA through membrane transport proteins
  3. CUptake of DNA through transient pores in the bacterial cell wall
  4. DExpression of antibiotic resistance gene

Correct answer

C. Uptake of DNA through transient pores in the bacterial cell wall

Step-by-step solution

Heat shock enables the bacteria to take up the recombinant DNA.
