Bacterial cells take up recombinant plasmids when they are treated with:
Correct answer: A. CaCl2
- A. CaCl2
- B. NaCl
- C. KCl
- D. NaOH
Explanation
CaCl2: This option is the correct answer. Bacterial cells are often treated with a solution of calcium chloride (CaCl2) during a process called "calcium chloride transformation" to increase their ability to take up recombinant plasmids. The treatment with CaCl2 helps to create temporary pores in the bacterial cell membrane, allowing the plasmids to enter the cells.
