In rDNA technology in order to make the bacterial host cells 'component' to accept the rDNA, these are kept in

A

Dilute solutoin of CsCl

B

Divalent anions such as phosphates

C

Chilled ethanol

D

Divalent cations such as calcium

Text Solution

Verified by Experts

The correct Answer is:
D
The cloning organisms or bacterial host cells (e.g. escheriohia coli ) are kept in specific concentration of divalent cations such as `Ca^(2+)`in order to make them more permeable and 'competent' for rDNA
