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.
Other antibiotics, such as penicillin, block the assembly of the bacterial cell wall causing it to weaken and burst.[7] Penicillin is an effective antibiotic for human diseases because it interferes with a biological component in bacteria (cell wall) not found in human cells.
