Mitotic phase during which daughter chromosomes move toward the poles of the spindle.

Formation of new blood vessels; one mechanism by which cancer spreads.

Programmed cell death involving a cascade of specific cellular events leading to death and destruction of the cell.

Short, radiating fibers produced by the centrosomes in animal cells.

Tumor that does not invade adjacent tissue and stays at the site or origin.

Malignant tumor whose nondifferentiated cells exhibit loss of contact inhibition, uncontrolled growth, and the ability to invade tissue and metastasize.

Development of cancer

Repeating sequence of events in eukaryotes that involves cell growth and nuclear division; consists of the stages G1, S, G2, and M.

Structure across a dividing plant cell that signals the location of new plasma membranes and cell walls.

Constricted region on a chromosome joining two sister chromatids.

Central microtubule organizing center of cells. In animal cells, it contains two centrioles.

In the cell cycle, one of several points where the cell cycle can stop or continue on, depending on the internal signal it receives; ensures that each step of the cell cycle is completed before the next one begins.

A single DNA strand of a chromosome. Chromosomes may consist of a pair of sister chromatids.

Network of fibrils consisting of DNA and associated proteins observed within a nucleus that is not dividing.

Structure consisting of DNA complexed with proteins that transmits genetic information from the previous generation of cells and organisms to the next generation.

In cell culture, the point where cells stop dividing when they become a one-cell thick sheet.

Protein that cycles in quantity as the cell cycle progresses; combines with and activates the kinases that function to promote the events of the cycle.

Division of the cytoplasm following mitosis and meiosis.

Synthesis of a new DNA double helix prior to mitosis or meiosis in eukaryotic cells and during prokaryotic fission in prokaryotic cells.

Protein molecule responsible for packing chromatin.

Stages of the cell cycle (G1, S, G2) during which growth and DNA synthesis occur when the nucleus is not actively dividing.

Enzyme that activates another enzyme by adding a phosphate group.

Invasive tumor that may spread.

Mitotic phase during which chromosomes are aligned at the spindle equator.

Spread of cancer from the place of origin throughout the body; caused by the ability of cancer cells to migrate and invade tissues.

Process in which a parent nucleus produces two daughter nuclei, each having the same number and kinds of chromosomes as the parent nucleus.

Process in which a parent nucleus produces two daughter nuclei, each having the same number and kinds of chromosomes as the parent nucleus.

Mitotic phase during which chromatin condenses so that chromosomes appear; chromosomes are scattered.

Molecule that stimulates or inhibits an event in the cell cycle.

One of two genetically identical chromosomal units that are the result of DNA replication and are attached to each other at the centromere.

Body cell; excludes cells that undergo meiosis and become sperm or egg.

Microtubule structure that brings about chromosomal movement during nuclear division.

Disk formed during metaphase in which all of a cell's chromosomes lie in a single plane at right angles to the spindle fibers.

Long, repeating DNA sequence at the ends of chromosomes; functions like a cap and keeps chromosomes from fusing with each other.

Mitotic phase during which daughter cells are located at each pole.

Cells derived from a single mutated cell that has repeatedly undergone cell division; benign tumors remain at the site of origin, while malignant tumors metastasize.
