Question
In Hershey and Chase experiments, radioactive P32 was used to culture bacteriophages which resulted in radioactive?
Open in App
Solution
The correct option is A Viral DNA
Bacteriophages produced within bacteria growing in radioactive culture medium will themselves be radioactive.
When bacteriophages containing 32P
(radioactive), were allowed to infect nonradioactive bacteria, all the
infected cells became radioactive and, in fact, much of the
radioactivity was passed on to the next generation of bacteriophages.
It was found that If radioactive phosphorus (32P) is used, the DNA become radioactive — because of its many phosphorus atoms.
