Answer #1

Passive transport

​​​​​​ DNA coated on gold nanoparticles is used for the delivery of foreign gene into the bacterial cell or some other vector.

Transduction is the process of of transfer of genes from one bacterium to the other with the help of virus.

Electroporation is the technique of incubating bacteria cells under an applied electric field so that it generates proes in the membrane of bacteria from where foreign gene can be taken by the bacterial cell.

Passive diffusion is the process of transport of molecules on their own from a region of high concentration to a region of low concentration. Foreign gene cannot be taken up by the bacterial cell on its own because inside the bacterial cell there is no foreign gene.

Please rate high.
