Unformatted text preview: –  Their genomes are circular –  Prokaryotes do not have a nucleus, mitochondria, or any other membrane- bound organelles –  The genome in a prokaryote is held within a DNA/ protein complex in the cytosol called the nucleoid. •  Eukaryotes –  Have nucleus (animal, plants, fungi) –  Linear genomes with mul7ple chromosomes in pairs 3 8/26/13 Prokaryotes vs. Eukaryotes Prokaryotes Eukaryotes Single cell Single or multi cell No nucleus Nucleus No organelles Organelles Polypolid Polyploid cells and organisms are those containing more than two paired (homologous) sets of chromosomes. Most eukaryp7c species are diploid, meaning they have two sets of chromosomes (one from each parent) One piece of circular DNA Chromosomes No mRNA post Exons/Introns splicing transcriptional modification Types of Polypolids •  triploid (three sets; 3x), for example watermelons, bananas, apples, citrus •  tetraploid (four sets; 4x), for example salmon fish, potato, comon •  pentaploid (five sets; 5x), for example Kenai Birch (plant) •  hexaploid (six sets; 6x), for example wheat, kiwifruit •  octaploid (eight sets; 8x), for example special types of fish (Acipenser), dahlias, •  decaploid (ten sets; 10x), for example strawberries •  dodecaploid (twelve sets; 12x), for example special types of the plants and amphibians What does Karyotype mean?
