Question
Biology Question on the molecular basis of inheritance
An analysis of chromosomal DNA using the Southern hybridization technique does not use
A
electrophoresis
B
blotting
C
autoradiography
D
PCR.
Answer
PCR.
Explanation
Solution
Southern hybridisation is a technique used in molecular biology for detection of a specific DNA sequence in DNA samples in which excepting PCR we use all three methods such as electrophoresis, blotting and autoradiography. Because PCR is the method used for the amplification of DNA sample. In vitro clonal propagation is characterised by PCR and RAPD.
