Question

Which one of the following is used as biosensors?
a) Electrophoresis
b) bioreactors
c) vectors
d) Electrophoration

Answer 1

The correct answer is option (d) electrophoration.

• Electroporation, or electropermeabilization, is the technique of microbiology in which the electric field is applied to cells to increase cell penetration, allowing chemicals, drugs, electrode arrays or DNA to be introduced into a cell (also called electrotransfer).
• In microbiology, the process of electroporation is often used to modify viruses, yeast, or plant protoplasts by introducing new coding DNA. When bacteria and plasmids are mixed together, plasmids can be transmitted to bacteria after electroporation, although depending on what is transmitted, peptides entering cells or CellSqueeze can also be used.

Answer 2

"Bioreactors" are used as biosensors. The correct option is (b) bioreactors.

Explanation:

1. Biosensors are devices designed to detect harmful pathogens in food items using measurable signals.
2. Bioreactors are used as biosensors.
