Only one variable should be tested in one experiment.
Changes in the shape of a cell usually involve a reorganization of the
cytoskeleton.
Cytoskeleton is an interwind filamentous network that mainly keeps and mantains the shape as well as internal organization.
- Hence reorganization is also done with the help of the cytoskeleton.
- Extracellular matrix mainly helps the cell to keep it together.
- Transporter proteins mainly act as a catalyzing agent for various purposes.
- Nucleus is just a genetic material carrying an organelle that regulates the activities of cells.

The factors are: The size of the sample, the extraction method, the method of purification and preservation of the DNA.
The quantity and quality of DNA can be greatly improved by performing PCR.
* Purification of nucleic acids is a key step for functional studies in biology. Because of the great diversity of living organisms in nature, purification becomes a real challenge for researchers, especially cell lysis.
The evolution of lysis methods has made it possible to improve efficiency, speed and simplicity. But, this lysis step remains a crucial step for the efficiency and the quality of the purification.
