Can normal E. coli cells carry resistance against antibiotics?

Options

  1. AYes
  2. BNo
  3. CIt depends
  4. DNone of the above

Correct answer

B. No

Step-by-step solution

Transformation is a procedure through which a piece of DNA is introduced in a host bacterium (you will study the process in subsequent section). Normally, the genes encoding resistance to antibiotics such as ampicillin, chloramphenicol, tetracycline or kanamycin, etc., are considered useful selectable markers for E. coli. The normal E. coli cells do not carry resistance against any of these antibiotics. .
