NEETZoologyMolecular Basis of Inheritance
Components Roles A. DNA with radioactive phosphorus 1. Did not show radioactivity in bacteria B. Proteins with radioactive sulfur 2. Entered the bacterial cell C. E. coli bacteria 3. Host for viral infection D. Blender 4. Used to separate viral coats from bacteria
Options
- AA - 2, B - 1, C - 3, D - 4
- BA - 1, B - 3, C - 4, D - 2
- CA - 4, B - 2, C - 1, D - 3
- DA - 2, B - 4, C - 3, D - 1
Correct answer
A. A - 2, B - 1, C - 3, D - 4
Step-by-step solution
A - 2: DNA with radioactive phosphorus entered the bacterial cell. B - 1: Proteins with radioactive sulfur did not show radioactivity in bacteria, indicating proteins did not enter the bacteria. C - 3: E. coli bacteria acted as the host for viral infection. D - 4: The blender was used to separate viral coats from bacteria by agitating them.
