Vedclass · Answer

(B) The incorrect statement is $B$. $ELISA$ (Enzyme-Linked Immunosorbent Assay) is based on the principle of antigen-antibody interaction. Infection by a pathogen can be detected either by the presence of antigens (proteins,glycoproteins,etc.) or by detecting the antibodies synthesized against the pathogen. Therefore,stating that it is checked 'only' by the presence of antigens is incorrect. Conventional methods like serum and urine analysis are not effective for early diagnosis,making statement $A$ correct. $GEAC$ (Genetic Engineering Appraisal Committee) is the body responsible for approving activities involving genetically modified organisms,making statement $C$ correct. An American company did indeed attempt to claim patent rights on Indian Basmati rice,making statement $D$ correct.
