ANAPHASE

The stage of mitosis or meiosis beginning with the separation of sister chromatids (or homologous chromosomes) followed by their movement towards the poles of the spindle.

CELLCYCLE

process of cellular reproduction, occurring in three main stages.

CENTROMERE

Centromere is important particularly during mitosis. Aside from being the region where chromatids are held and kinetochore is formed, it also serves as the point of attachment for spindle fibers

CHROMATIN

relaxed form of DNA in the nucleus of the cell.

CHROMOSOME

DNA-containing structure that carries genetic material from one generation to another.

CYTOKINESIS

third main stage of the cell cycle, during which the cell's cytoplasm divides, creating a new cell.

INTERPHASE

first stage of cell cycle, during which a cell grows, matures, and replicates its DNA.

METAPHASE

The stage of mitosis (and meiosis) following prophase and preceding anaphase

MITOSIS

second main stage of the cellcycle during which the cell's replicated DNA divides and two genetically identical diploid daughter cells are produced.

PROPHASE

Classical term for the first phase of mitosis or of one of the divisions of meiosis. During this phase the chromosomes condense and become visible.

SISTER CHROMATIDS

Two identical strands joined by a common centromere as a result of a chromosome that duplicated during the S phase of the cell cycle.

SPINDLE APPARATUS

Any of a network of filaments that collectively form a mitotic spindle (in mitosis) and meiotic spindle (in meiosis). It is chiefly involved in moving and segregating the chromosomes during nuclear division.

TELOPHASE

The final stage of mitosis or meiosis, when chromosome separation is completed. The final stage of mitosis.The final stage of meiosis when the chromosomes move toward opposite ends of the nuclear spindle.
