Then, the new viruses that were made were all labeled with the 32P, meaning that the DNA that was injected into the bacterium is what was used to produce the new viruses. This shows that DNA is what contains genetic material, not proteins. DNA as genetic material in eukaryotes and the use of RNA

The chromosomal components were isolated but the material which is responsible for inheritance remained unanswered. Griffith’s experiment was a stepping stone for the discovery of genetic material. It took a long time for the acceptance of DNA as genetic material. Let’s go through the discovery of DNA as genetic material.

The extraction of DNA from a cell is often a first step for scientists who need to obtain and study a gene. The total cell DNA is used as a pattern to make copies (called clones) of a particular gene.

Thus, the Hershey–Chase experiment helped confirm that DNA, not protein, is the genetic material. Hershey and Chase showed that the introduction of deoxyribonuclease (referred to as DNase ), an enzyme that breaks down DNA, into a solution containing the labeled bacteriophages did not introduce any 32 P into the solution.
