Document Summary

Made up of at least one molecule of nucleic acid + a capsule made of protein. Sometimes also an envelope (most animal viruses) Many shapes, some even look like a lunar lander! A cell (of any kind, not even prokaryote) They do not perform any cellular functions. They can not do anything by themselves. Makes copies of itself using the cell"s resources: 1 enters the cell 100+ leave. They infect any organism they can get their hands on. There is at least 1 virus for every kind of organism. The virus can not synthesize anything; it does not have any cell like stuff. In fact, they only affect your own cells. Nucleic acids span the gamut when it comes to viruses. Viruses can be classified according to the type of molecule carrying their genetic information. Dsdna (like humans) e. g. papillomavirus, poxvirus, t4. Ssrna, positive sense e. g. rhinovirus (common cold) This virus carries a messenger rna with itself.
