Unformatted text preview: Cell Cycle, Mitosis and Meiosis Cell Division is essential for life Reproduction, growth, development, repair & renewal, replacement Unicellular organisms reproduce by cell division Binary Fission (Prokaryotes) 1 chromosome replicates moves to opposite poles of the cell No microtubules (spindle apparatus) to help Why do we need to know? Bacterial cell division In binary fission (Bacterial cell division) The bacterial chromosome replicates The two daughter chromosomes actively move apart Eukaryotic Cells Multicellular organisms use cell division for development (from a fertilized egg), growth, and repair, replacement and maintenance Cell Division (mitosis & cytokinesis) falls within the cell cycle. Cell Division is a very small part of the cell cycle Genetic Material Genome Varies in size (prokaryotic vs. eukaryotic) DNA packaged into chromosomes (chromatin and proteins) DNA diffused in nucleus during interphase Chromosomes condense, visible at mitosis (and meiosis ) Chromosome Related Terms...
