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:. (The DNA Virus). Prepared by:. Miss . Norzawani. . Jaffar. Bsc. (. Hons. ) Biomedical Sciences, UKM. Lecture 17. Learning Outcomes. At the end of this learning session, student must be able to;. Classify the viruses. EQ: Why are viruses considered to be non-
living?. Characteristics:. *Nonliving particles made of . nucleic acid. and a . protein coat . enlosed in a . capsid. shell... *In order to reproduce, all viruses must have a . 8.1 What Is a Virus?

Viruses enter a . host. . cell. and use the host’. s biosynthetic machinery to reproduce and synthesize its proteins. Draw the basic structure of a virus. Label and define capsid, viral envelope and nucleic acid.. Ch. 17 Warm-up. Draw the lytic/lysogenic cycle.. What stage of the lytic-lysogenic cycle is a virus virulent? Temperate?. DNA . is a molecule in your cells’ nuclei that can be . used as instructions by your cells . to make new cells, and pigments for your hair and skin.. What is DNA again?.

Dr. Baha Eldin Khalid Elamin. Viruses enter the body of the host. in a variety of ways, for example... . .  .                                             . 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.. “Computer.” . –. Brad. “Flu.” . –. Sydney. “HPV.” . –. Corley. “No.” . –.
