The experiments by hershey and chase confirm that dna was the hereditary material on the basis of the finding that:
a. radioactive phage were found in the pellet
b. radioactive cells were found in the supernatant
c. radioactive sulfur was found inside the cell
d. radioactive phosphorus was found in the cell

Option D

Explanation:

Hershey and Chase were the scientist that concluded that DNA is the genetic material which is transferred from one generation to another generation.

Before their experiment, people used to believe that protein is the genetic material.

Hershey and Chase conducted an experiment on bacteriophage where Radioactive phosphrous was transferred along with DNA in the cell.

This proved that DNA is the genetic material that transferred information from one generation to another.

economic impact of malaria is estimated to cost africa $12 billion every year. this figure factors in costs of health care, absenteeism, days lost in education, decreased productivity due to brain damage from cerebral malaria, and loss of investment and tourism.

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.
