Question

The “Ti plasmid” of Agrobacterium tumefaciens stands for

• A. Tumour inhibiting plasm
• B. Tumor independent plasmid
• C. Tumor inducing plasmid
• D. Temperature independent plasmid

Answer 1

The Correct Option is C

The Ti plasmid of Agrobacterium tumefaciens is well-known for its role in plant pathology. The term "Ti plasmid" stands for "Tumor inducing plasmid." This is because the plasmid carries genes that can integrate into a plant's genome, resulting in the formation of tumors, also known as crown gall disease. Let's break down the significance of this plasmid:

• Function: The Ti plasmid allows Agrobacterium tumefaciens to transfer DNA to plant cells, causing them to proliferate uncontrollably, similar to rapid tumor growth.
• Composition: It contains genes responsible for the transfer and integration of a specific segment of DNA (T-DNA) into the plant's genome.
• Use in Biotechnology: Scientists utilize Ti plasmids in genetic engineering to introduce new genes into plants due to their natural ability to transfer DNA across species.

The correct answer is Tumor inducing plasmid.
