NEETZoologyMolecular Basis of Inheritance
Terms Descriptions A. S strain 1. Non-virulent, lacks a polysaccharide coat B. R strain 2. Genetic material responsible for transformation C. Heat-killed S strain 3. Virulent, has a polysaccharide coat D. Transforming principle 4. Could not cause disease when injected alone
Options
- AA - 3, B - 1, C - 4, D - 2
- BA - 1, B - 4, C - 3, D - 2
- CA - 4, B - 2, C - 1, D - 3
- DA - 2, B - 3, C - 1, D - 4
Correct answer
A. A - 3, B - 1, C - 4, D - 2
Step-by-step solution
A - 3: The S strain is virulent and has a smooth polysaccharide coat. B - 1: The R strain is non-virulent and lacks a polysaccharide coat. C - 4: The heat-killed S strain could not cause disease when injected alone. D - 2: The transforming principle refers to the genetic material responsible for the transformation observed in Griffith's experiment.
