Q.Which one of the following is not correct statement.

Step 1. Test option (a). The chapter states plainly that Agrobacterium tumefaciens, carrying the Ti plasmid, is 'responsible for inducing tumours in several dicot plants' - specifically crown gall disease, not 'bunchy top disease' (a name associated with a different, virus-caused banana disease entirely unrelated to the Ti plasmid). This statement is incorrect.

Step 2. Test option (b). The chapter states that a vector's unique restriction sites are 'Multiple Cloning Site (MCS) or polylinker' - so calling the MCS a polylinker is correct.

Step 3. Test option (c). The chapter's glossary defines transfection as 'Introduction of foreign nucleic acids into cells by non-viral methods' - so this statement is correct as printed. …

Check each of the four statements individually against the chapter's stated facts on the Ti plasmid, polylinkers, tr …

• Assuming any disease name mentioning plants must be the correct one for the Ti plasmid, without checking it is actually crown gall. …
