Centromere

Area where the chromatids of a chromosome are attached.

Chromatids

Bodies of tightly coiled chromatin; visible during cell division. Two chromatids bound at a centromere make a CHROMOSOME.

Prophase

Chromosomes coil; become shorter and thicker and join at the centro meter. Nuclear membrane disappears. Centrioles form and move away from each other protein spindle fibers form. Centrioles move away from each other pushed towards seperate ends, Nucleur membrane disintergrates,. chromotin form chromosomes Longest phase

Metaphase

Chromosomes pair up and line up in the center (or middle) of the cell. Centromeres of duplicated chromosomes are aligned at plate. Fully formed spindle attach to the sister chromatids from opposite poles

Anaphase

Chromosomes separate pull on the spindle fibers and move toward opposite sides of the cell to the opposite poles. Centromere split in half, spindle fibers pull chromosomes to opposite pole.

Cytokinesis

Two new cells are formed. Cell enters again into interphase. Completes the cell division process by dividing the cytoplasm into two daughter cells, each with a nucleus

Mitosis

A process of nuclear division in eukaryotic cells conventionally divided into five stages: prophase, prometaphase, metaphase, anaphase, and telophase. Mitosis conserves chromosome number by equally allocating replicated chromosomes to each of the daughter nuclei.

Telophase

New nuclear membranes form around the chromosomes. Cytoplasm begins to divide (Cytokinesis.) After the chromosome seperates, the cell seals off, Final Phase of Mitosis. A cleavage furrow forms during this phase

Interphase

Phase between mitosis stage. Time for cell growth and development. Chemical changes leading to cell division are taking place. DNA replicates. A period between two mitotic or meiotic divisions during which the cell grows, copies its DNA, and synthesizes proteins
