Meiosis Terms Microtubule - One of three protein components of the cytoskeleton. Long, cylindrical structures approximately 25 nanometers in diameter. Extend from the centrosome to all parts of the cell, forming tracks on which organelles can travel within the cell. Prometaphase 1 - The second stage of the first meiotic division (meiosis I), during which the nuclear envelope breaks down, allowing microtubule access to chromosomes. Prometaphase 2 - The second stage of the second meiotic division (meiosis I), during which microtubules attach to chromosomes. Prophase 1 - The first stage of the first meiotic division (meiosis I), during which genetic reassortment takes place. Can be very long occupying up to 90% of the entire duration of meiosis.

Unformatted text preview: Prophase 2 - The first, brief stage of the second meiotic division (meiosis II), during which condensed chromosomes are visible. Sister chromatid - Refers to the copy of a chromosomes that results from DNA replication and is still closely linked to its original. Somatic cell - Any plant or animal cell that is not a germ cell. The class of cell formed during mitosis. Telophase 1 - The fifth and final stage of the first meiotic division (meiosis I), during which chromosomes arrive at the poles of the cell and begin to recondense. Telophase 2 - The fifth and final stage of the second meiotic division (meiosis II), during which chromosomes arrive at the poles of the cell, the nuclear envelope begins to reform, and the chromosomes begin to recondense....
