Explain hoe foreign DNA is inserted into the host
Transduction is the insertion of foreign DNA into a cell via a virus.
Transformation is a way that bacterial cells pick up pieces of DNA from their environment.
Injection is a common way of introducing foreign DNA into plants is to physically inject the DNA with a gene gun.
The Ti plasmid of agrobacterium has a region called the T-DNA, which is cut out of the plasmid and carried by bacterial proteins out of the bacteria into the plant cell. Insertion of foreign DNA into the T-DNA region by restriction enzymes is one way that scientists insert genes into plants.
