Vedclass · Answer

(B) Sulphur is a key component of certain amino acids,specifically cysteine and methionine,which are the building blocks of proteins. $DNA$ and $RNA$ do not contain sulphur. When bacteria or bacteriophages are grown in a medium containing radioactive sulphur $(^{35}S)$,this isotope is incorporated into the cysteine and methionine residues during protein synthesis. Consequently,the resulting proteins become radioactive. This principle was famously used in the Hershey-Chase experiment to distinguish between protein and $DNA$ as the genetic material.

$A$ bacterium grown on a medium containing radioactive Sulphur incorporates the radioactivity into:
