Molecular biological techniques have developed with the study of viruses. One such technique used to help confirm the existence of viruses was
A) clarified sap of infected plants was used to produce novel antigens in rabbits after exposure.
B) birefringence was observed in sap after it was cooled and sonicated.
C) novel antibodies were created by rabbits exposed to sap from plants infected with tobacco mosaic virus.
D) treated sap produced a polarisation of light that suggested spherical or dodecahedral shaped particles.
E) All of the options listed are correct.

Question

Quizplus · Accepted Answer

The technique described in option C, where novel antibodies were created by rabbits exposed to sap from plants infected with tobacco mosaic virus, is a classic example of an early molecular biological technique used to study viruses. This method involves using the immune response of an organism (in this case, rabbits) to confirm the presence of viral particles in the sap of infected plants, demonstrating the existence and nature of the virus.
