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 guide, to demonstrate that perhaps the injection itself has no impact on the cell cycle.

A successful experiment has handled the same control group as the experimental group with the exception of the variable being examined, in this case the cytoplasm M-phase.

what have scientists found to be the most efficient and effective way to insert new sequences into an individual? a-scientists have created genetically altered foods that release dna during digestion. b-scientists use viruses to insert specific gene sequences. c-scientists irradiate genes so that they can be absorbed through the skin.

micro/nanoscale topography surface exhibits many prominent properties and is extensively employed in biomedical device, microfluidic device and energy device fabrication. additionally, the clinical applications of biomaterials can be largely expanded with of nanostructured surfaces.
