Answer:
The correct answer is option d. "Polyclonal antibodies".
Explanation:
The enzyme-linked immunosorbent assay (ELISA) is very useful in comparison to other immunoassay methods for being highly accurate, sensitive and specific. Polyclonal antibodies for the detection step could be used on order to ensure that a mutation in a single surface protein would not make obsolete an ELISA used to detect a new viral pathogen. Unlike monoclonal antibodies, polyclonal antibodies are a collection of antibodies that recognize multiple epitopes of the same antigen. Therefore, a mutation in one epitope that affects the binding of one antibody would not affect the bind of the others and the ELISA will be able to recognize the pathogen.
Answer:
copper is found in a rock called chalcopyrite
Answer:
A protein needed for blood clot formation.
Explanation:
Prothrombin may be defined as the protein that changes in to the thrombin during the process of blood coagulation with the help of clotting factor X.
The main function of the prothrombin protein is the coagulation of blood. This protein is responsible for blood clotting at the time of external and internal injury.
Thus, the correct answer is option (c).
1 is catalyst
2 is substrate
3 is active site
4 is activation energy
5 is ions
6 is ion
7 is denature
