Question

Which molecules on a virus are not found on host cells?

a) Pathogen-associated molecular patterns (PAMPs)
b) Pattern recognition receptors (PRRs)
c) MHC I and II molecules
d) Somatic receptors on T and B lymphocytes

Answer 1

Pathogen-associated molecular patterns (PAMPs) on a virus are not found on host cells.

Step-by-step explanation:

The molecules on a virus that are not found on host cells are Pathogen-associated molecular patterns (PAMPs). PAMPs are carbohydrate, polypeptide, and nucleic acid 'signatures' expressed by viruses, bacteria, and parasites, but they differ from molecules on host cells. They are recognized by pattern recognition receptors (PRRs), which are membrane-bound receptors found on the cells of the innate immune response.
