Question

Choose the correct answer from the alternatives given :
Match column I with column II and select the correct option from the given codes.

	Column I		Column II
A.	Griffith	(i)	Lac operon
B.	Hershey and Chase	(ii)	Semi-conservative DNA replication
C.	Meselson and Stahl	(iii)	Transduction
D.	Jacob and Monad	(iv)	Transformation

• A. A - (iv), B - (iii), C - (ii),D - (i)
• B. A - (iii), B-(iv), C - (ii),D - (i)
• C. A - (iv), B - (ii), C - (iii),D - (i)
• D. A - (ii), B - (i), C - (iii), D - (iv)

Answer 1

Answer: (A)

A - (iv), B - (iii), C - (ii),D - (i)

Griffith performed the transformation experiment on S.pneumoniae to prove that the genetic material was inheritable. Hershey and Chase performed the transduction experiment which is the infection of a bacteria by a virus called bacteriophage to prove that DNA and not proteins were the genetic material. Meselson and Stahl the experiment on E.coli to establish that replication was semi-conservative (half of parent and half synthesized). Jacob and Monad elucidated the Lac operon a transcription-ally regulated system.

So, the correct option is 'A - (iv), B - (iii), C - (ii),D - (i)'.
