Q. Which one of the following is a case of wrong matching ?
A) Callus - Unorganised mass of cells produced in tissue culture
B) Somatic hybridization - Fusion of two diverse cells
C) Vector DNA - Site for t-RNA synthesis
D) Micropropagation - In vitro production of plants in large numbers
Explanation
[Solution from source] A vector DNA (such as a plasmid) carries the foreign gene into the host cell and lets it replicate; it is not a site of tRNA synthesis. Callus, somatic hybridisation and micropropagation are all correctly described. Answer (3).
