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.
Penicillin was the first antibiotic made available to humans during World War II. It was very effective against gram-positive bacteria, but didnât last long and was susceptible to stomach acid so was wasted inside the body. Amoxicillin is the new and improved version of penicillin that is able to last longer, resist stomach acid, and kill both gram-positive and gram-negative bacteria. It is often used to prevent and treat infections found in cuts and wounds, the mouth, the upper respiratory system, and the bladder. Amoxicillin also has better absorption than another predecessor, Ampicillin.
