PPT-What is a virus?

Viruses They lack a cell membrane Dont have a nucleus Dont have organelles They have a variety of shapes They are too small to be seen unless you use the electron microscope How do they multiply. 1.

Viruses Are Not Cells!. 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:. Technology is Evolving. Computer’s have become smaller, faster, and more efficient. Many new helpful devices. Heavy Dependency of Technology: Y2K. Technology causes the evolution of different programs. Instructions. You may use your notes.. Write your answers in the spaces provided.. This review is due at the end of the period!. 1.

Classify the viruses. The influenza virus group consists of three enveloped RNA members of the family Orthomyxoviridae:. influenza A, B, and C. . Influenza A . viruses are further classified into hemagglutinin (H) and neuraminidase. . Outside . their host cells, viruses survive as . virus particles. , also known as . virions. . The . virion. is a . gene delivery . system; it contains the virus genome, and . its functions . are to protect the genome and to aid its . 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.. Most viruses exhibit a limited host range- they typically infect only specific types of cells of one host species..
