Obtain and Use Energy. Since the discovery by Enders (1949) that polioviruses could be cultured . in tissue. , cell culture has become a very useful and convenient method for isolating viruses in vitro. Viral isolation in cell culture still remains the "gold standard" for many cultivable viruses . Focal Documents. Assessment Creator. Science Assessment Update. Science STAAR Analysis Publishing Date.

The DNA instructions are really a pattern of 4 different chemicals read as a code by the cell’s nucleus.. Where are cases of viral hemorrhagic fever found Taken together the viruses that cause VHFs are distributed over much of the globe However because each virus is associated with one or more particular Viruses consist of a nucleic acid (either DNA or RNA) associated with proteins encoded by the nucleic acid. The virus may also have a lipid . bilayer. membrane (or envelope) but this is acquired from the host cell, usually by budding through a host cell membrane. If a membrane is present, it must contain one or more viral proteins to act as . ANSWERS CAN BE FOUND IN CHAPTER 19 SECTION 2 on VIRUSES (you need to look at the WHOLE SECTION)..

The term virus means ‘poison’.. Most of them are disease causing . Have a complex mechanism of hijacking the machinery of the host genome for its self replication.. Viruses are very small – smaller than the smallest cell.. They are usually surrounded by a capsid of proteins.. For replication, viruses rely on their host cells . ie. ., the cells they infect..
