There are several structural and functional differences between cells and viruses. The structural differences include:. No nucleus. No cell membrane. No organelles. The functional differences include:. The Ebola virus causes an acute, serious illness which is often fatal if untreated. . The most severely affected countries are: Guinea, Sierra Leone and Liberia. These country have very weak health systems, lacking human and infrastructural resources.. Thea Brennan-Krohn (“BK”). July 2010. Polyomaviruses. Small DS DNA viruses. Cause “poly” “. omas. ”.

They are usually surrounded by a capsid of proteins.. For replication, viruses rely on their host cells . ie. ., the cells they infect.. Most viruses exhibit a limited host range- they typically infect only specific types of cells of one host species..
