Ti plasmid transforms cells of
Ti plasmid transforms cells of
The correct option is B Plants
Ti plasmid:
The Ti plasmid or tumour inducing plasmid (extrachromosomal DNA) is carried by Agrobacterium tumefaciens. The T-DNA segment of the Ti plasmid integrates itself into the plant cell’s genome to induce tumour formation in plants. This property of the plasmid makes it an effective vector for transferring foreign genes into plant cells.
Disarmed pathogen:
Disarmed pathogen is the method used for transferring the recombinant DNA into the host cells, like animal cells. It is created by replacing the gene responsible for the pathogenic effect with the alien gene. For example: Disarmed retroviral vectors are used for transferring genes in animal cells.
Plasmid:
Plasmids are extracellular double-stranded, autonomously replicating DNA used as vectors for small fragments of DNA. It is commonly used in bacterial gene cloning.
Yeast artificial chromosomes:
Genetically engineered DNA obtained from Saccharomyces cerevisiae. It is used to clone DNA sequences. Up to one million base pairs can be inserted into these chromosomes. YACs are commonly used in yeast cells
Final answer
