The technique in which foreign DNA is precipitated over surface of metal particles for passing into target cells is:
Open in App
Solution
The correct option is C Particle gun
In molecular biology, transformation of cell is an important step. It involves direct uptake and incorporation of foreign DNA from the surrounding which can be done by:
The particle gun/biolistic method is a technique in which tungsten or gold particles coated with foreign DNA are bombarded into target cells to facilitate entry of the foreign genes.
Microinjection is the introduction of foreign genes into plant or animal cells using micropipettes or glass needles.
Electroporation is creating transients (temporary pores) in the plasma membrane to facilitate entry of foreign DNA.
Chemical mediated genetic transformation: It involves certain chemicals such as polyethene glycol (PEG), that help in the uptake of foreign DNA into host cells.
