Cellular Reproduction Assignment
By: Richard Walsh
What is the Purpose of this assignment?
• The Purpose of this assignment is to educate
you on some very important terms that deal with
cell reproduction.
• These terms include:
•
•
•
•
•
•
•
Anaphase
Centromere
Chromatin
Chromosomes
Cytokenisis
Daughter Cell
Cell Cycle
What Exactly is Anaphase?
• Anaphase- A late stage of cell division during which
the Centromere spits apart and chromosomes
move to the poles of the spindle.
< Anaphase occurring in a cell.
What is a Centromere?
• Centromere – The point at which two parts (sister
Chromatids) of a chromosome join and at which the
spindle fibers are attached during mitosis. Also called
kinetochore.
Centromere >
What is Chromatin?
• Chromatin - A complex of nucleic acids and proteins,
primarily histones, in the cell nucleus that stains readily with
basic dyes and condenses to form chromosomes during cell
division.
Chromatin >
What are Chromosomes?
• Chromosomes - A
threadlike linear strand of
DNA and associated
proteins in the nucleus of
eukaryotic cells that
carries the genes and
functions in the
transmission of hereditary
information.
^Chromosomes as they occur in
the human body.
What does the process of Cytokenisis mean?
• Cytokenisis - Organic process consisting of the
division of the cytoplasm of a cell following
karyokinesis bringing about the separation into
two daughter cells.

What is a Daughter Cell?
• Daughter Cell - Either the two cells produced during mitosis
of the parent cell.

What is a Cell Cycle?
• Cell Cycle - The
series of biochemical
and structural events
involving the growth,
replication, and
division of a
eukaryotic cell.
