results from the separation of sister chromatids during cell division
having the same structure and pair during meiosis
region that holds the two sister chromatids together
type of cell division that results in two identical daughter cells
any cell of a living organism other than the reproductive cells
time period where the cell grows, copies DNA, and synthesizes proteins
first stage of cell division; chromosomes becomes visible as paired chromatids, nuclear envelope disappears
second stage of cell division; chromosomes become attached to the spindle fibers
third stage of cell division; chromosomes move away from one another to opposite poles
final stage of cell division; nuclear membrane forms around each set of new chromosomes
division of the cytoplasm; divides into two daughter cells
protein structures that pull apart the sister chromatids during cell division
cell division that results in the production of sex cells (gametes)
the process by which male gametes form; spermatozoa (sperm)
the process by which female gametes form; ovum (eggs)
