Question

Chemical mediated gene transfer can be facilitated using:

• A.
  Ethidium bromide
• B.
  5’–bromo uridine
• C.
  Poly ethylene glycol
• D.
  Poly acrylamide

Answer 1

The correct option is C

Poly ethylene glycol
One of the most important chemicals used for vector less gene transfer is Polyethylene Glycol or PEG. It is the most commonly used for gene transfer in organisms like bacteria (Escherichia coli) and yeast cells (Saccharomyces cerevisiae).
