what is difference between virus and prions and bacteria
Answers
Answer:
==========================================
The structures of all three of these subjects are very different. Bacteria have three different shapes known as streptococci, which are chains of cocci that are spherical or oval-shaped. Escherichia coli lives in your intestines and is rod-shaped. And vibrio’s that are spiral-shaped. In bacteria, DNA and RNA are floating in the cytoplasm. Bacteria have a cell wall, a cell membrane, flagella, and ribosomes but do not have a nucleus. Viruses are sub-microscopic particles, about 20-300 nanometers. They have two main parts: a capsid which is composed of protein subunits and an inner core of nucleic acid, either DNA or RNA. They also have spikes made from a glycoprotein. Viruses have no cell wall, but they have a protein coat instead. They don’t have a nucleus also.
