The hershey-chase experiment used a blender and a centrifuge. contemplate the importance or unimportance of these devices to the overall results and choose which statement is true.

a) if the blender had been used but no centrifuge, it would have yielded the same basic results, with dna being the heritable material.

b) the blender was a preliminary test step but was unnecessary. the centrifuge would have created the same separation and yielded the same results—dna being the heritable material.

c) the centrifuge was used to make the work of studying the results with a microscope easier, but it still could be seen that both the inside and the outside of the bacterial cells were always labeled had only a blender been used. the valid conclusion would be dna as heritable material.

d) without the blender, the protein coat would have stayed on the bacteria cell membrane. this would cause the results to be that both the protein and the dna were parts of the heritable material.
