These would be any cells that reproduce asexually, like bacteria
The primary role of DESMOSOME is to blind animal cells together. It is the formation of a structure from protein plaques in the cell membranes linked by filaments. This links to a the protein that is attached to the cell surface adhesion.
The human gene for insulin production is identified and removed using enzymes called restriction enzymes. The same restriction enzymes are used to cut open a plasmid (a small, circular section of DNA).
