02_12 Cell Cycle and Mitosis

Cell Cycle

the ordered series of events involving cell growth and cell division that produce two new daughter cells; composed of G1, S, G2, and Mitotic phases

Mitosis

The series of events that result in the distribution of one copy of the genetic material to each of two daughter cells at the end of cell division.

Cytokinesis

The physical division of the cell at the end of mitosis; it is marked by the formation of the cleavage furrow in animal cells and the formation of the cell plate in plant cells.

Chromosome

A big piece of DNA with genes on it

Condensed chromosome

the tightly wrapped, packed state of a chromosome during mitosis

Duplicated chromosome

a single chromosome composed of two copies of the DNA is contains packaged as two sister chromatids connected at the centromere

Spindle Apparatus

the network of cytoskeletal elements (microtubules) that forms during prophase of mitosis that directs the movement of chromosomes during mitosis

PMAT

an acronym for the phases of mitosis: Prophase, Metaphase, Anaphase, and Telophase

Chromatid

half of a duplicated chromosome containing one complete copy of the DNA of that chromosome for cell division
