Q200 / 200 · NEET 2012 (Screening) · Zoology

Which one of the following is a case of wrong matching?

A
Somatic hybridization - Fusion of two diverse cells
Correct answer
B
Vector DNA - Site for tRNA synthesis
C
Micropropagation - In vitro production of plants in large numbers
D
Callus - Unorganized mass of cells produced in tissue culture

Solution

A vector is a DNA molecule used as a vehicle to transfer foreign genetic material into desired cell. the tRNA is synthesized in the nucleus on a DNA tempelate. Only $0.025 \%$ of total DNA content codes for tRNA.

Hence, the correct answer is option: 'B'.
