Prokaryotic Cell Eukaryotic Cell Multiple linear Si l i l DNA (chromatin) Multiple, linear chromosomes reside in nucleus Single, circular chromosome Stimulus initiates Controlled by Cell Cycle Simple fission; chromosome cell division duplicates, cell splits in two: Æ form clones Interphase: G1-S-G2; h form clones chromosomes replicated Di l id ti Di l id ll Eukaryotes: accurate Diploid somatic cell undergoes mitosis : form 2 Diploid sex cell undergoes meiosis : form 4 movement & partitioning of chromosomes requires microtubules & diploid clones genetically distinct haploid gametes requires microtubules & formation of spindle during mitosis/meiosis
