50. In vitro clonal propagation in plants is characterized by:

[2014]

(a) PCR and RAPD

(b) Northern blotting

(c) Electrophoresis and HPLC

(d) Microscopy

Show Answer

Answer : a

Hints & Solutions

(a) Now a days PCR and RAPD technique are used for the characterisation of in vitro clonal propagation in plants. Random amplified polymorphic DNA (RAPD) is a PCR based technique for identifying genetic variation. It involves the use of a single arbitrary primer in a PCR reaction, resulting in the amplification of many discrete DNA products.
