The answer given to last question which i asked was wrong ,kindly recheck and confirm the answer please

Dear student,

Bacteriophages produced within bacteria growing in radioactive culture medium will themselves be radioactive. If radioactive sulphur atoms (35S) are present, they will be incorporated into the protein coats of the bacteriophages since two of the amino acids — cysteine and methionine — contain sulphur. However, the DNA will be nonradioactive because there are no sulphur atoms in DNA. If radioactive phosphorus (32P) is introduced instead, the DNA become radioactive — because of its many phosphorus atoms — but not the proteins.
