Eukaryotic and prokaryotic cells share the presence of:
- cytoplasm, in which their organelles are dispersed.
-the cell membrane, which covers the cell by shaping and regulating the passage of substances (in and out of it).
- ribosomes, are the place where proteins are synthesized.
In addition, both cells possess DNA although this is not the same in both. In the eukaryotic cell it is linear and is within the nucleus, while in the prokaryotic cell it is circular and does not have a true nucleus that protects it.
The α and β subunits of the insulin receptor form two bands in the SDS-PAGE gel. Moreover, in the Western blot analysis, there is just one band corresponding to the β subunit, since this subunit contains phosphorylated tyrosines, while α subunit doesn't have.
