binary fission
A form of asexual reproduction in which one cell divides to form two identical cells.
Nucleus
A part of the cell containing DNA and RNA and responsible for growth and reproduction
nuclear membrane
controls what goes in and out of the nucleus
Chromosome
a threadlike body in the cell nucleus that carries the genes in a linear order
Centromere
the point on a chromosome by which it is attached to a spindle fiber during cell division.
Chromatin
Substance found in eukaryotic chromosomes that consists of DNA tightly coiled around histones
Chromatid
one of two identical "sister" parts of a duplicated chromosome
Mitosis
part of eukaryotic cell division during which the cell nucleus divides
Cytokinesis
Division of the cytoplasm during cell division
cell cycle
series of events that cells go through as they grow and divide
G1 phase
stage of interphase in which cell grows and performs its normal functions
G2 phase
stage of interphase in which cell duplicates its cytosol and organelles
S phase
The synthesis phase of the cell cycle; the portion of interphase during which DNA is replicated.
M phase
The phase of the cell cycle that includes mitosis and cytokinesis.
Prophase
Chromosomes become visable, nuclear envelop dissolves, spindle forms
Metaphase
second phase of mitosis, during which the chromosomes line up across the center of the cell
Anaphase
Phase of mitosis in which the chromosomes separate and move to opposite ends of the cell
Telophase
After the chromosome seperates, the cell seals off, Final Phase of Mitosis.
mitotic spindle
a structure made of microtubules that controls chromosome movement during mitosis
Equator
Where the 2 hemispheres of a sphere meet
Centrioles
Cell organelle that aids in cell division in animal cells only
