Question
_______A______ is a protein produced by the cells invaded by _____B_____.
The correct options are:
_______A______ is a protein produced by the cells invaded by _____B_____.
The correct options are:
Open in App
Solution
The correct option is B A - Interferons, B - virus
Interferons are a group of glycoproteins produced by the viral infected cells. It is an antiviral protein as it interferes with the multiplication of viruses. It offers resistance by blocking viral mRNA transcription. Interferons signal neighbouring cells to destroy viral RNA and reduce protein synthesis. It activates other immune cells also. It has anticancer properties too. So option a is correct.
Histamine and serotonin are chemicals released by basophils, a type of white blood cells. They are associated with inflammatory reactions like pain, redness and swelling in the area affected. They are not associated with viral infections.
A cell when infected with bacteria, it results in the production of antibodies not interferons, histamine or serotonin to protect the cells.
