Mitosis — The equal division of the cell's genome (DNA) 2. Cytokinesis — The division of the cytoplasm, membranes, and other organelles The Basics of Cell Division • When a cell divides, each daughter cell must receive a complete genome • Prior to cell division, a cell's DNA is duplicated, DNA replication • During cell division, this DNA is segregated equally into the two daughter cells —Each cell receives a complete genome Chromosome duplication • The entire genome must be duplicated before cell division • In prokaryotic cells (i.e. bacteria), the genome is single circular DNA molecule, but in eukaryotic cells (i.e. us), the genome divided among multiple

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
