Assume saccharomyces cerevisiae is grown in a nutrient medium containing the radioisotope 35p. After a 48-hour incubation, the 35p would most likely be found in the s. Cerevisiaeʹs

After a 48-hour incubation, the 35S would most likely be found in the S. cerevisiae's proteins.

35S is the isotope of sulfur with the half-life of 87.6 days. It is often used isotope because it is low energy β emitter and even large amounts of 35S pose no external dose hazard to exposed organism. 35S is used for the examination of protein synthesis in the Saccharomyces cerevisiae cell cycle.
