Hide Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Understand Ti plasmids.
Ti plasmids are found in \textit{Agrobacterium tumefaciens}, a bacterium that causes crown gall disease in plants. These plasmids can transfer a piece of DNA into the plant genome.
Step 2: Use of Ti plasmids in genetic engineering.
Scientists have harnessed the ability of Ti plasmids to deliver foreign genes into plants, making them one of the most important tools in plant genetic engineering.
Step 3: Identify the host.
While Ti plasmids can be found in bacteria, they are used to deliver genes into plant cells, not animal, virus, or bacterial cells.
Step 4: Conclusion.
Since Ti plasmids are primarily used for genetic modification in plants, the correct answer is (C) Plant.
Final Answer: Ti plasmid vectors are used to deliver genes into plant hosts.

Top Questions on Biotechnology
The vector, shown in the figure, has promoter and RBS sequences in the 300 bp region between the restriction sites for enzymes X and Y. There are no other sites for X and Y in the vector. The promoter is directed towards the Y site. The insert containing only an ORF provides 3 fragments after digestion with both enzymes X and Y. The ORF is cloned in the correct orientation in the vector using the single restriction enzyme Y. The size of the largest fragment of the recombinant plasmid expressing the ORF upon digestion with enzyme X is ........... bp. (answer in integer)
