Question

Name the source from which Ti plasmid is isolated. Explain the use of this plasmid in biotechnology.

Answer 1

Ti plasmid (Tumour-inducing plasmid) is an extra-chromosomal DNA isolated from Agrobacterium tumefacians. It is used in biotechnology as a cloning vector as it removes the tumor-inducing genes from the host. It helps to insert a foreign gene of interest in the target DNA.
