Question

pls....answer with reason!!!!!​

Answer 1

Answer:

Evidence from Experiments with Bacteriophage ( T2 )

Explanation:

★ Hershey and Chase demonstrated that only DNA of the bacteriophage enter the bacterial cell and therefore contains necessary genetic information for the assembly of new phage particle.

» Therefore ;

=> Bacteriophage DNA was labelled with radioactive phosphorus ( P³² ) by growing bacteria .

=> Also ; Bacteria infected in culture medium containing ( P³²O4 ) .

=> Thus ; the protein coat of Phage voice labelled with radioactive sulphur molecule ( S³⁵ ) .

According to Question ;

★ What viruses are produced if T2 phage having Sulphur infects bacteria ?

» So ; In real experiment Sulphur was labelled on protein coat of bacteriophage

so ; we would be not able to found it in Dna .

Answer :- Option A

Radioactive Capsid ( coat ) and Non radioactive Dna

» [ Because Phosphorus is not labelled in dna According to Question ; so it only can trace protein coat of phage not phage dna ]
