Zoology - Molecular Basis of Inheritance Question with Solution | TestHub

The polysaccharide capsule ofStreptococcus pneumoniaeis the dominant surface structure of the organism and plays a critical role in virulence, principally by interfering with host phagocytic clearance mechanisms. The S-strain bacteria synthesize a smooth polysaccharide coat and are virulent, while the R-strain bacteria synthesize a rough polysaccharide coat and are non-virulent.
