ELISA technique is based on the principle of antigen-antibody interaction. Can this technique be used in the molecular diagnosis of a genetic disorder, such as phenylketonuria?

Assertion: ELISA is based on the principle of antigen antibody interaction Reason :Infection by pathogen can be detected by the presence of antigens or by detecting antibodies synthesized against the pathogen

Assertion : ELISA test is based on antigen-antibody interactions where a pathogen can be detected by the presence of antibodies (proteins,glycoproteins, etc) on it Reason : The pathogen antibody to be identified is immobilised on the surface of specially constructed ELISA plates and is then tested.

Carbon dioxide is an essential component of atmosphere. However, when the concentration of CO_2 increases in the atmosphere, it can lead to global warming through green house effect. Similarly, rain water is an essential source of water. It has pH of 5.6 due to the formation of H^+ ions from the reaction of rain water with CO_2 present in the atmosphere. When pH of the rain water falls below 5.6 due to the presence of acids in the atmosphere, it has very damaging effects. Name two main acids present in acid rain. From where do these acids come in acid rain ?
