The experiments by Hershey and Chase helped confirm that DNA was the hereditary material on the basis of the finding that :
Correct answer: D. Radioactive phosphorus was found in the cell
- 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
Explanation
The experiments by Hershey and Chase helped confirm that DNA was the hereditary material as radioactive phosphorus was found in the cell.The Hershey-Chase experiments were not the first studies to oppose the prevailing theory in the early 1900s that genetic material was composed of proteins. In 1944, nearly a decade before Hershey and Chase's work, scientists published sound evidence that genes were made of DNA rather than protein so it was confirmed by presence of phosphorus.

About Chromosomes
Chromosomes are DNA-protein structures that carry genes and become visible during cell division. Coverage includes chromatin, centromeres, sister chromatids, homologous chromosomes, chromosome number, and the distinction between diploid and haploid cells, with links to DNA replication, mitosis and meiosis.
