WebThese translocations along with those of other proteins led to the realization that D. discoideum has a semi-open mitosis as opposed to a closed mitosis as previously … The primary result of mitosis and cytokinesis is the transfer of a parent cell's genome into two daughter cells. The genome is composed of a number of chromosomes—complexes of tightly coiled DNA that contain genetic information vital for proper cell function. Because each resultant daughter cell should be genetically identical to the parent cell, the parent cell must make a copy of eac…
