Stages of Cell Divison

Cell cycle

Changes cell goes through from fomation to divison

Interphase

Is the longtiest phase last most of the cells time carrying out normal activities

When it is about to divide it will replicate DNA during this phase

Mitosis Miotic phase

Cell reproduces itself through cell division

Mitosis division of copied DNA into two daughter nuclei

Cytokinesis when the cell itself divides

Interphase 2

Not part of mitosis

DNA is in chromatin form threadlike and not condensed

DNA is replicated

Prophase

Chromatin needs to condense to chromosomes

Duplicated chromosomes are sister chromatids

When separated they each will be a new chromosome

Held by centromere

Metaphase

Our sister chromatid are still together and chromosomes line up at the midline

Ezymes act on the centromere to separate them

Anaphase

Centromeres split

Each sister chromatid is a separate chromosome

Begin to move apart

Short condensed chromosomes are easily moved than tangled stringy chromatin

Telophase

Begins when the chromosomes finsih moving apart

Uncoil into chromatin form

Nuclear envelope forms around each mass of chromatin

Mitosis complete

Cytokinesis

Cytoplasm divides and cells are pinched apart

Meiosis

Makes gametes that have half the normal chromosomes haploid

Nongametes are diploid they have twice the number of chromosomes

Yields four distinct daughter nuclei
