Answer:
c) Negri bodies are a diagnostic sign of Rabies virus infection.
Explanation:
Rabies is an infection caused by rabies virus which affects the neurons and causes inflammation of the brain. It is a deadly disease and many animals are carriers of this disease like dogs, cats, raccoons, wolf, bats, fox, etc.
It is diagnosed by the presence of Negri bodies in the cytoplasm of nerve cells. Negri bodies are inclusions that are round or oval shapes having a size between 0.25 to 27 μm. Negri bodies can be frequently diagnosed in Purkinje cells of the cerebellum and pyramidal cells of Ammon’s horn.
Apart from these cells, they can be found in various ganglia, neurons of the tongue and other organs. So the correct answer is c.

Hi,
If a point mutation occurs during which CGA changes to AGA, the mutation will be simply inherited to the offspring and there won't be any harsh effects on the health of individual.
This is because, both AGA and CGA code for same amino acid called Arginine.
We know that mutations posses harmful effects when they change the genetic sequence leading to the incorporation of incorrect amino acid in the organisms and their offspring. But in this case the mutation will not be harmful and will simply be transferred to the offspring and will have no effect on the functioning, fitness or survival of the organism
