The Hershey and Chase experiments showed that the inherited genetic material was DNA (deoxyribonucleic acids). In this experiment, the scientists labelled the DNA molecule with a radioactive isotope of phosphorus.
Centrifugation causes the separation of different components according to their size. So, by blending, they centrifugated the mixture of virus and the bacteria, which separated the viral protein capsule and the bacteria. Later, they found that the virus infected bacteria contains the DNA of bacteria, not the protein.
Hence, bacterial cultures infected with a virus were agitated in a kitchen blender to separate the protein coat of virus from the bacteria.
The answer is C. <span>Sister chromatids align in the middle; cytoplasm pinches in to separate daughter cells.</span>
