It occurs during Anaphase II, Telophase II, and Cytokinesis, when the sister chromatids separate so that there is 1 allele per gamete.
The sulphur would lable the capsule and the phosphorous the nucleic acid.
<h3><u>Explanation</u>:</h3>
Hershey and Chase experiment included growing of the pages in two batches, one in presence of 35S and other in presence of 32P. They then infected bacterial cells with these phages, cleaned them and then centrifuge the cells to isolate the marked elements in bacterial cells.
This was done to isolate which part of the phage is actually infective. Sulphur being a part of the proteins will mark the capsule whereas DNA having the phosphate bridges will be marked by 32P.
