*Cell contains a nucleus and other membrane bound organelles not in bacteria but in human body..
*DNA occurs in a circular form* in bacteria only..
* Ribosomes size in bacteria 70s and in human body 80s
*Capable of growth at temperatures greater than 80 C only in bacteria
*His tone proteins present in cell only in human body cells
* Operons present in DNA only in bacteria..
