During Meselson and Stahl' experiments, heavy DNA was distinguished from normal DNA by centrifugation in

A

CsOH gradient

B

`""^(14) NH_(4)`Cl

C

`""^(15) NH_(4) Cl`

D

CsCl gradient

Text Solution

Verified by Experts

The correct Answer is:
D
Messelson and Stahl experimented with E. coli grow in radioactive isotope `15 NH_(4) Cl` and `14 NH_(4)`Cl and can be distinguished between these two isotopes by centrifugation in Cscl gradient. This experiment explain semi-conservative mode of replication
