Answer 1

31- B- False

32- B false it may used for 2 antibodies

in principle and is not restricted to serum antigens, nor is it required to use the indirect method of measuring the free antigen instead of directly measuring the captured antigen. For example, if it is undesirable or not possible to radiolabel the antigen or target molecule of interest, a RIA can be done if two different antibodies that recognize the target are available and the target is large enough (e.g., a protein) to present multiple epitopes to the antibodies. One antibody would be radiolabeled as above while the other would remain unmodified. The RIA would begin with the "cold" unlabeled antibody being allowed to interact and bind to the target molecule in solution. Preferably, this unlabeled antibody is immobilized in some way, such as coupled to an agarose bead, coated to a surface, etc.

33- A true case e.g.Adrenal competence develop due to removal od adrenal gland inhibit ACTH etc.

34- A true

35- A true By GPCR

36- A true

37- A true

38- A true

39- A true

40- A true but both the cases are seen u can manipulate by single gene or via multiple copies of gene
