Mitosis and cancer Flashcards
The type of nuclear division in which the daughter cells have the same number of chromosomes as the parent cell.
Mitosis
The cells that are produced by cell division.
Daughter cell
Chromatid
One of the two strands of a chromosome that are joined together by a single centromere prior to cell division. Each contains a double helix DNA
The place where the two copies of DNA after replication are joined together.
Centromere
The period of the cell cycle when the cell is not dividing.
Interphase
The first stage of mitosis when the chromosomes become visible and when spindle fibres develop. The nucleolus disappears and the nuclear envelope breaks down.
Prophase
The stage of mitosis when the chromosomes arrange themselves across the equator of the cell.
Metaphase
Anaphase
The third stage of mitosis when the centromeres divide into two and the spindle fibres pull the individual chromatids making up the chromosome apart to their respective, opposite poles of the cell.
Telophase
The fourth stage of mitosis when chromosomes reach their respective poles and become longer and thinner, finally disappearing altogether, leaving only widely spread chromatin. The spindle fibres disintegrate and the nuclear envelope and nucleolus re-form.
When the cytoplasm divides.
Cytokinesis
Spindle fibres
These form the spindle apparatus which are responsible for pulling the chromatids to separate ends of the cell.
Centrioles
Where the spindle fibres develop from in animal cells.
Where the chromosomes arrange themselves during metaphase.
Equator
The process by which cell division occurs in prokaryotic cells.
Binary Fission
A group of diseases caused by a growth disorder of cells as a result of damage to the genes that regulate mitosis and the cell cycle which results in uncontrolled growth and division of cells.
