Chapter 17, Problem 13MC
Summary Introduction
Introduction:
Monoclonal antibodies are antibodies (identical) produced by specialized immune cells. They are a derivative of cell division from a single parental cell. They have monovalent affinity that can attach with same epitope. They are used as a drug to treat arthritis, lupus, cancer, and so on.

3. What is the major benefit of cross-reactivity?
A. Cross-reactivity permits the allergic response.
B. Cross-reactivity promotes a faster immune response against unrelated pathogens.
C. Cross-reactivity enhances immunity by providing protection against related pathogens.
D. Cross-reactivity allows the immune system to respond to pathogens in various locations within the host (i.e., skin, mucosal tissues, extracellular fluids, etc.)
