All cells, whether they are prokaryotic or eukaryotic, have some common features. The common features of prokaryotic and eukaryotic cells are: 1  DNA, the genetic material contained in one or more chromosomes and located in a nonmembrane bound nucleoid region in prokaryotes and a membrane-bound nucleus in eukaryotes.
Penicillin antibiotics are used to treat treat urinary tract infections, upper respiratory tract infections, lower respiratory infections, skin infections, bacterial infections, gastrointestinal infections, meningitis, and pneumonia. They work by killing the bacteria that is causing the infection.
  Without fully explaining how the penicillin antibitic works: yes, archaea are resistant to penicillin. This is because they don't have peptidoglycan in their cell wall. â¦ Penicillin works by lowering the newly formed peptidoglycan in multiplying bacteria.It also does other things.The reason it works (this is natural penicillin G) only on Gr+ is because the can't get through the GR-cell wall.his is because they don't have peptidoglycan in their cell wall. â¦ Penicillin works by lowering the newly formed peptidoglycan in multiplying bacteria. It also does other things.
