What are the genes encoding resistance to antibiotics commonly considered as useful selectable markers for E. coli?

Options

  1. AAmpicillin
  2. BChloramphenicol
  3. CTetracycline
  4. DAll of the above

Correct answer

D. All of the above

Step-by-step solution

In addition to ‘ori’, the vector requires a selectable marker, which helps in identifying and eliminating non transformants and selectively permitting the growth of the transformants. 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
