    Study Notes

    Cell Division in Multicellular Organisms

    • Cell division is necessary for growth, repair, and maintenance of tissues in multicellular organisms.

    Cell Division in Unicellular Organisms

    • The purpose of cell division in unicellular organisms is to reproduce and increase the population.

    Genome

    • A genome is the complete set of genetic information contained within an organism's DNA.

    Genome Organization in Prokaryotes

    • In prokaryotes, the genome is organized into a single circular chromosome.

    Human Somatic Cells

    • Human somatic cells have 46 chromosomes, arranged into 23 pairs.
