Modeling Mitosis

 

In our science class, we have started to learn about biology. our first section was how does the cell work? and what are all the roles of the cell parts? Now our next section we will be taking about mitosis. we have used yarn, pipe cleaners and string, to form all the phases of PMAT+ interphase, and cytokinesis.

Interphase

Interphase is the time when the cell is doing its normal activity interphase is the longest cell stage, it is when the cell performs and grows. During interphase the cell replicates it’s DNA, adds proteins and  organelles that the cell needs to do its job.

* Interphase isn’t a phase in mitosis, its just what the cells does regularly.

Early prophase

 

Early prophase is  the first part of Prophase.  the phase starts of by the nucleolus leaving the cell, and then spindle fibers form.

the chromatin starts to become chromones, and getting ready for the next stages .

Late prophase

 

Late prophase is  the second part of prophase. the spindle fibers are completely developed. The spindle fibers connect with centromeres of chromosomes, when the spindle fibers connect with the centromeres of chromosomes. 

the nuclear membrane has fully diapered.

Metaphase

 

Chromosomes composed of sister chromatids, will separate and align themselves in a matter that they are on the equator of the cell.

 

Anaphase

the spindle fibers pull sister chromatids to complete opposite sides of the cell.{ preparing them to be separated for the next phase}

Telophase

telophase is the last stage in PMAT. The spindle fibers has vanished and a nuclear membrane begins to form around each set of chromosomes {that happened last phase} The new cells are still connected to each other, but in the next stage they will be there own.

 Cytokinesis

*not a stage in PMAT

Cytokinesis is the separation of the nuclei into 2 new daughters cells.
