- To destroy viral particles
Why are ultracentrifuges particularly useful for studying viruses
Why are ultracentrifuges particularly useful for studying viruses
- They can sediment even the smallest viruses (correct)
- They allow viruses to multiply rapidly
- They prevent viral contamination
- They reduce the infectivity of viruses
What is the main principle behind rate-zonal centrifugation?
What is the main principle behind rate-zonal centrifugation?
- Particles are separated based on their buoyant density
- Particles move at different rates depending on their mass (correct)
- Particles aggregate at the bottom of the centrifuge tube
- Particles are destroyed through high-speed spinning

What is the primary role of ultracentrifuges in virology?
What is the primary role of ultracentrifuges in virology?
To separate and concentrate viruses based on their size and density.
Why are ultracentrifuges particularly useful for studying viruses?
Why are ultracentrifuges particularly useful for studying viruses?
They can isolate even the smallest viruses by separating them based on their sedimentation rate in a density gradient.
What is the main principle behind rate-zonal centrifugation?
What is the main principle behind rate-zonal centrifugation?
This method separates particles based on their size and sedimentation rate. Larger and denser particles move faster through the gradient.
