Q. Why are mice killed by smooth (S) strains of Streptococcus, but not rough (R) strains?
Molecular Basis of Inheritance
A
Rough strains are virulent, and smooth strains are not.
B
Rough strains have a polysaccharide capsule that makes the mouse immune system recognize and destroy them.
C
Smooth strains have a polysaccharide capsule, which hides them from the mouse immune system.
D
Smooth strains grow faster than rough strains.
Solution:
Correct answer is (c) Smooth strains have a polysaccharide capsule, which hides them from the mouse immune system.
