Answer: All of the above.
Chase and Hershey conducted experiments in 1952, using bacteriophages that revealed DNA, not protein, was the genetic material.
The experiments that revealed protein was not the genetic material were conducted by Martha Chase and Alfred Hershey in 1952. They were studying a bacteriophage, a virus that infects bacteria, which has two main structures: a protein coat known as the capsid, and a nucleic acid core that contains either DNA or RNA.
Hershey and Chase used radioactive markers to label the protein coat and DNA of the bacteriophage, respectively. Through their experiments, Hershey and Chase discovered that only the DNA entered the host bacteria upon bacteriophage infection, suggesting that DNA, not protein, is the genetic material. Their work was instrumental in establishing DNA as the molecule responsible for heredity.

Losing cutaneous sensations can have serious consequences, including difficulty in manipulating objects, risk of self-injury from not feeling pain, and potential burns or frostbite from not sensing temperature changes.
The cutaneous senses include pain (nociception), temperature (thermoception), and touch (including pressure, texture, vibration). Loss of these senses may result in severe consequences.
