Final answer:
The T plasmid is designed for the introduction of genes into plant cells, utilizing a method where Ti plasmids from Agrobacterium tumefaciens are modified and used as vectors.
Step-by-step explanation:
The T plasmid is used for introducing genes into c) Plant cells. This plasmid originates from the bacterium Agrobacterium tumefaciens and is frequently utilized as a shuttle vector for genetically modifying plants. The natural ability of Ti plasmids to transfer into plant cells has been harnessed by researchers, who can remove the tumor-inducing genes and replace them with genes of interest to produce transgenic plants. The T plasmid carries the foreign gene and facilitates its insertion into the plant cell's chromosome.
The T plasmid is used for introducing genes into:Prokaryotic cells: The T plasmid can be easily introduced into prokaryotic cells through a process called transformationPlant cells: Shuttle vectors, such as the T plasmid, can be used to introduce genes into plant cells by transferring the T-DNA carrying the foreign gene into the plant cell's genome.
