Prokaryotic Chromosome vs Eukaryotic Chromosome
• Found in cytoplasm.
• Circular chromosome attached to the inside of the cell membrane.
• Single chromosome plus plasmids.
• Made only of DNA.
• Copies its chromosome and divides immediately afterwards.
• Found in nucleus
• Linear chromosomes
• Many chromosomes.
• Usually,10-50 chromosomes in somatic cells.
• Human body cells have 46 chromosomes.
• Made of chromatin, a nucleoprotein (DNA coiled around histone proteins).
• Copies chromosomes, then the cell grows (G2 phase), then goes through mitosis to organise chromosomes in two equal groups.
