    Study Notes

    Characteristics of Living Things

    • Living things are distinguished from nonliving matter by their ability to grow, respond to stimuli, reproduce, metabolize, and maintain homeostasis.

    Cell Division and Genome

    • The result of most cell division is two daughter cells that are genetically identical to the parent cell.
    • A prokaryotic cell's genome consists of a single circular chromosome.

    Cell Cycle and Mitosis

    • The main role of cell division in growth and development is to produce new cells that can differentiate into various cell types.
    • The phases of mitosis are responsible for the equal separation of chromosomes into two daughter cells.
    • The main function of the S phase in interphase is DNA replication.
    • DNA replication occurs during the S phase of the cell cycle.
    • Cell division occurs only if the cell is large enough and the DNA is undamaged.
    • Mitosis is the stage of the cell cycle where the cell nucleus divides.

    Gametes and Meiosis

    • Gametes (reproductive cells) have half the number of chromosomes as somatic cells.
    • Gametes are distinguished from other daughter cells by their unique genetic makeup and ability to fuse with other gametes during fertilization.
    • Meiosis yields daughter cells that have half the number of chromosomes as the parent cell.

    Chromosomes and DNA

    • The characteristic number of chromosomes in each cell nucleus of eukaryotic species varies, but is typically diploid (2n).
    • Gametes have half the number of chromosomes as somatic cells.
    • The narrow 'waist' of the duplicated chromosome is called the centromere.
    • In a typical human cell, the DNA is approximately 2 meters long when fully extended.

    Cell Cycle Pattern

    • The regular pattern of growth, DNA replication, and cell division is called the cell cycle.
