TERM 1
centriole
DEFINITION 1
A centriole is a barrel-shaped cell structure found in most
animal eukaryotic cells, though absent in higher plants and
most fungi.
TERM 2
cyclin dependent
DEFINITION 2
Cyclin-dependent kinases (CDK) belong to a group of protein
kinases originally discovered as being involved in the
regulation of the cell cycle.
TERM 3
cytokinesis
DEFINITION 3
Cytokinesis, from the greek cyto- (cell) and kinesis (motion,
movement), is the process in which the cytoplasm of a single
eukaryotic cell is divided to form two daughter cells.
TERM 4
meiosis
DEFINITION 4
In biology, meiosis (pronounced ) is a process of nal division
in which the number of chromosomes per cell is cut in half.
TERM 5
mitosis
DEFINITION 5
Mitosis is the process by which a eukaryotic cell separates
the chromosomes in its cell nucleus into two identical sets in
two nuclei.

TERM 6

chromatid

DEFINITION 6 A chromatid is one among the two identical copies of DNA making up a replicated chromosome, which are joined at their centromeres, for the process of cell division (mitosis or meiosis). TERM 7

chiasmata

DEFINITION 7 The term chiasma comes from the Greek , which is related to the Greek letter and means "crossing". TERM 8

kinetochore

DEFINITION 8 The kinetochore (pronounced: knt'kr) is the protein structure on chromosomes where the spindle fibers attach during division to pull the chromosomes apart.
