Calcium chloride helps in:

Options

  1. ARestriction of foreign dna
  2. BFormation of pores on cell wall
  3. CDegradation cell membrane
  4. DExonuclease activity

Correct answer

B. Formation of pores on cell wall

Step-by-step solution

When Ca2+ ions are rubbed against the cell wall, it results in the enlargement of the diameter of the pores and allows the uptake of foreign DNA fragments.
