The key difference between virus and prion is that the virus is a tiny infectious particle composed of nucleic acids and a protein coat while the prion is a small infectious particle composed of a single protein. There are different types of biological entities studied by microbiologists. Among them, virus and prion are two types […]

The key difference between bacteria and viruses is that the bacteria can live without a host organism while the viruses cannot live without a living host. Many people think that both bacteria and viruses are germs that are harmful to human beings. Furthermore, they think that viruses and bacteria belong to the same category that […]

The key difference between molds and yeasts is that the molds are multicellular filamentous fungi whereas the yeasts are unicellular round or oval fungi. Kingdom fungi are one of the five kingdoms that include eukaryotic microorganisms such as yeasts, molds rusts, smuts, mildews and mushrooms. They are very vital and useful decomposers in the environment […]
