In an experiment to determine whether M-phase cells contain a regulatory molecule that initiates mitosis, cytoplasm from M-phase cells and interphase cells was injected separately into interphase cells. Why did researchers inject cytoplasm from interphase cells?

as a negative control to show that the injection itself doesn't have an effect on the cell cycle

  

as a positive control because they knew interphase cytoplasm would drive the injected cells into mitosis

  

because they wanted to see if interphase cells also contained a regulatory molecule that initiates mitosis

  

None of the listed responses is correct.
