Bacteriophage .They used the radioactive isotope sulfur-35 to label the of the virus and phosphorus-32 to label the of the virus
. They allowed the tagged virus to infect bacteria and studied the results. Hershey and Chase found that the only radioactive isotope within the bacteria was . This result indicated that the genetic material inserted by the virus to infect the bacteria was DNA .
Bacteriophage is nothing but a virus that harms and kills the bacteria.
The Hershey-Chase Experiments is a well known experiment done by scientist, Alfred Hershey and Martha Chase. They conducted the experiment in the year 1952.
It was an extra ordinary experiment which made the world believe that the DNA is the genetic material and not a protein. In their experiment, they tried to find out if the protein coat or the core of the DNA of the virus which enters into the infected cells would help them to understand whether the genes were made of DNA or of protein.
They used sulfur-35 and phosphorus-32 radioactive isotopes to trace the DNA and the proteins.
Changes in natural flow regimes as a result of water extraction and supply direct modification or destruction of important habitat barriers to the movement of the plants and animals.
Explanation: It is not possible because if you draw a punnett square you see that the only phenotype you get is Cc. C (curly hair) is dominant over c (straight hair) so curly hair will always be expressed.
