Answer #1

Answer:(c) interferon

Interferons are low-molecular weight- proteins that prevent viral multiplication by stimulating the production of antiviral proteins in normal cells. Interferon activity is host specific rather than virus specific.

  • Antibody or immunoglobulins are protein molecules that are able to combine with antigenic determinant.
  • They are found in the serum and other body fluids such as gastric secretion and milk. Antigen is a molecule capable of interacting with specific components of the immune system.
  • The portion of the antigen that is reactive with a specific antibody or T-cell receptor is called, epitope. Histones are basic proteins, which binds with DNA molecule to form nucleosome.

1. Neutralizing antibodies are effective at preventing infection or toxicity mediated by pathogens or their toxic products. In fact, nearly all vaccines currently in use function by eliciting neutralizing antibodies. The most important feature of a neutralizing antibody is: A. Having a high degree of multi-valency, such as being a pentamer or hexamer of immunoglobulin monomers B. Having high affinity for the antigen C. Being present at a high concentration in the circulation D. Being efficient at activating the complement...
