True! All DNA molecules have the same amount of charge per mass. Because of this, gel electrophoresis of DNA fragments separates them based on size only. Using electrophoresis, we can see how many different DNA fragments are present in a sample and how large they are relative to one another.
Hope this helps!
Answer: E- Cytokinesis is not part of mitosis. The 4 Phases of Mitosis are Prophase, Metaphase, Anaphase, and Telophase.
Explanation: Cytokinesis isn't truly mitosis or interphase, but a stage of it's own. It happens at the end of mitosis and is often included in explanations of mitosis.
Anaphase, is the stage of mitosis when replicated chromosomes are split and the daughter chromatids are moved to opposite poles of the cell.
