Solution

The correct option is C Assertion is correct but Reason is incorrect.
Protein engineering is the design of new enzymes or proteins with new or desirable functions. It is based on the use of recombinant DNA technology to change amino acid sequences. Monoclonal antibodies are monospecific antibodies that are made by identical immune cells that are all clones of a unique parent cell. These are made by fusing myeloma cells with the spleen cells from a mouse that has been immunised with the desired antigen.
Therefore, the correct answer is option C.
