Mitosis key words 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
One of the two strands of a chromosome that are joined together by a single centromere prior to cell division
Chromatid
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 second stage of mitosis when the chromosomes arrange themselves across the equator of the cell
Metaphase
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
Anaphase
The fourth stage of mitosis when chromosomes reach their respective poles and become longer and thinner, finally disappearing altogether, leavind only widely spread chromatin. The spindle fibres disintegrate and the nuclear envelope and nucleolus re-form
Telophase
When the cytoplasm divides
Cytokinesis
These form the spindle apparatus which are responsible for pulling the chromatids to separate ends of the cell
Spindle fibres
Where the spindle fibres develop from in animal cells
Centrioles
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
Cancer
