Mitosis Phases
the part of the cell cycle is not dividing
Interphase
Cytokinesis
Division of the parent cells cytoplasm
DNA
A molecule that contains the information that determines the traits that a living thing inherits and needs to live. (inherits it's parents' cells)
sister chromatids
Duplicate copies of DNA attached at a
cell cycle
An ordered sequence of events in the life of a cell
Chromatin in the nucleus of the cell gets smaller and becomes visible
Prophase
Mitosis
The part of the cell cycle during which the nucleus divides.
DNA provides information for?
cell growth and function
Chromosomes
DNA is duplicated or copied. Then in an early stage of cell division, the chromatin is compacted into visible structures called chromosomes
chromatids are held together by a
centromere
Metaphase
In metaphase, the chromosomes line up across the center of the cell
In cytokinesis
The cytoplasm divides and 2 new cells are produced
Why is it important for DNA to be duplicated before mitosis?
To make sure that after cell division it gets the exact copy
Chromatin
Made up of DNA and proteins
spindle fibers
protein fibers that attach to chromatids and assist in their separation during mitosis.
The chromatids separate. They are pulled to opposite sides of the cell.
Anaphase
During interphase
the cell carries out normal life
What happens when cells divide
DNA is copied
Loose chromatin is compacted into what?
chromosomes
How many daughter cells are produced?
Each cells divides once and produces 2 daughter cells which are genetically identical to each other and the parent cell
The new nuclear membranes forms around each group of chromosomes.
Telophase
The four phases of Mitosis
Prophase, metaphase, anaphase, telophase
Where is DNA found?
nucleus
a chromosome is made of compacted
chromatin
3 Roles of cell division
Reproduction, growth, repair
