Mitosis and Cytokinesis Flashcards

Flashcards covering mitosis and cytokinesis focusing on definitions.

Mitosis

Asexual reproduction where a parent cell duplicates to make 2 identical daughter cells.

Chromosomes

Condensed chromatin, each half of the X is called a chromatid.

Sister Chromatids

Two identical chromatids held together by the centromere.

Centromere

The point at which sister chromatids are held together.

Prophase

The stage where chromatin condenses into chromosomes, the nuclear membrane breaks down, and centrioles move to opposite poles.

Microtubules

Spindle fibers that develop from the centrioles during cell division.

Chromatin

DNA + protein, uncoiled and found during interphase.

Chromosome

Tightly coiled DNA, shown as an X.

Chromatid

Identical copies of the same chromosome joined together at the center.

Metaphase

The stage where chromosomes line up in the middle of the cell 'equator' and spindle fibers attach to the centromere.

Anaphase

The stage where spindle fibers shorten and split the centromere, separating sister chromatids into daughter chromosomes.

Daughter Chromosomes

Sister chromatids that have separated during anaphase.

Telophase

The stage where chromosomes become thinner, a new nuclear membrane forms around each group of daughter chromosomes, and the cell forms a nucleus again.

Cleavage Furrow

Area where indenting begins during telophase in animal cells.

Cytokinesis

Final stage of cell division where the cytoplasm divides.

Cell Plate

Structure that develops between daughter cells in plant cells during cytokinesis, eventually forming a new cell wall.
