उत्तर
Two vectors less methods of gene transfer used in rDNA technology.
- Chemical mediated gene transfer: Use of chemicals like polyethylene glycol (PEG) and dextran sulphate induces DNA uptake by plant protoplasts.
- Electroporation: Short electric impulse of high voltage causes fine transient forces in the cell membrane through which foreign DNA enters into the cell.
