Answer:
E. The 32P was associated with the bacterial cells and 35S was associated with the phage particles.
Explanation:
Hershey and Chase's experiment proved that DNA serves as the genetic material of the cell.
This experiment used the bacteriophage which could infect the bacteria by integrating its DNA into the bacterial genome. For this, he used radioactive phosphorus and radioactive sulphur.
Phosphorus is a constituent of the DNA and sulphur is the constituent of the proteins. This means if the DNA is transferred, then radioactive Phosphorus will be transferred but if proteins are transferred then radioactive sulphur is transferred.
He found the radioactive phosphorus attached to the bacteria and sulphur to the phage itself. This suggested that the DNA material is transferred and acts a hereditary material and not the protein.
Thus, Option-E is correct.
The hippocampus is associated with memories for events and facts, known as Episodic memory whereas the cerebellum is associated with memories for skills and abilities, known as procedural memory.
Explanation:
Storage of memory is not the work of a particular part of brain but it is associated with several parts such as amygdala, hippocampus, cerebellum etc.
Hippocampus is the part of emotional brain and plays a great role in remembering events or episodes and recognition.
The cerebellum is the part of the brain that associates itself with learning and skill development.
