Viruses have the ability to evolve by changing their genetic material

Viruses contain genetic material found inside their capsid

Viruses mature over time from past encounters


Describe the typical structure of a virus. What is a virus made of? What biomolecules would you find in a virus? A virus has a segment of genetic material which is inside a protein cost called a capsid. There are also some enzymes found inside the capsid. The biomolecules found in a virus

Discuss the different ways viruses gain entry into a cell. A virus can enter a host cell by attaching itself to a certain receptor on the cell's surface. A virus can get a 'ride from something that can enter the cell without being caught.

Explain why the Ebola virus would not infect a tobacco plant. The ebola virus would not infect a tobacco plant because the plant has antibodies that can kill the Ebola virus.

Name five viruses and the type of cell they attack.

HIV infects Helper T-Cells. Measles attack Dendritic cells. The Varicella zoster viruse attacks sensory nerve cells.The stomach flu attacks stomach cells. Myrocarditis attacks heart cells.

You have been diagnosed with the flu. Explain why a doctor will not provide you with a prescription for antibiotics in order to cure your infection. a doctor will not give you any antibiotics because viruses are not living organisms.

How is it that a person can be infected with a virus such as HIV and not exhibit symptoms? The virus can sneak inside a cell and stay inactive for a long time before attacking.
