P. Limited proteolysis of rabbit IgG with the enzyme pepsin generates two antigen-binding regions (Fab) and an Fc fragment.
Q. Limited proteolysis of rabbit IgG with the enzyme papain generates a single bivalent antigen-binding region F(ab')2 and peptide fragments.
R. The Fc fragment of IgG can self-associate and crystallize into a lattice.

A human problem to be brought to a human solution requires human data and human tools". Who said this?

Determine the correctness or otherwise of the following Assertion (A) and Reason (R).
Assertion: An antigen recognized by one immunoglobulin subtype is not recognized by any other subtype.
Reason: Immunoglobulin subtypes differ from each other both in the variable and in the constant regions.

True breeding Drosophila flies with curved wings and dark bodies were mated with true breeding short wings and tan body Drosophila, The F1 progeny was observed to be with curved wings and tan body. The F1 progeny was again allowed to breed and produced flies of the following phenotype, 45 curved wings tan body, 15 short wings tan body, 16 curved wings dark body and, 6 short wings dark body. The mode of inheritance is

A student appeared in the Mock CAT. The test paper contained 3 sections namely QA, DI and VA. The percentage marks in all VA was equal to the average of percentage marks in all the 3 sections. Coincidentally, if we reverse the digit of the percentage marks of QA we get the percentage marks of DI. The percentage marks in VA scored by student could be:
