<span>Glycolysis is a process that can be seen as occurring in eukaryotic cells. This process is active when cellular energy levels are low; and the regulatory enzyme is inhibited by ATP. This process releases energy that is labeled as 'free'. After this process the released energy goes to form ATP molecules, which are high in energy.</span>
The two cells that result from a single cell need to have the same amount of genetic material as the initial cell, therefore the DNA needs to be duplicated before the cell divides.
The sister chromatids are attached together so that during anaphase the daugther cells will receive the same chromosomes
