There are 5 test tubes having a culture medium containing rough colonies of streptococcus pneumoniae. The following substances were added in them. Which of these test tubes will show smooth colonies of streptococcus pneumoniae on incubation for some time? Test tube I: RNA from a heat-killed smooth strain of streptococcus pneumoniae Test tube II: DNA from a heat-killed smooth strain of streptococcus pneumoniae Test tube III: Protein from a heat-killed smooth strain of streptococcus pneumoniae Test tube IV: Carbohydrate from a heat-killed smooth strain of streptococcus pneumoniae Test tube V: Heat killed smooth strain of streptococcus pneumoniae incubated with DNAse enzyme

Proteins that contain tyrosine develop yellow colour when heated with HNO_(3) . This test is known as

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.
