The protein coat of a virus.

What is the capsid?

The nucleic acid in a retrovirus.

What is RNA?

A structure that surrounds the protein coat of some viruses.

What is an envelope?

The shape name represented by this virus.

What is filovirus?

The two shapes that make a binal virus.

What are polyhedral and helical?

The first step in viral reproduction.

What is the virus must attach to the cell (membrane)?

The 2 cycles for viral reproduction.

What are Lytic and Lysogenic?

The cycle represented by this diagram.

What is the lytic cycle?

The cycle in which the viral DNA is inserted into the host’s DNA then the host cell divides.

What is the lysogenic cycle?

The way the virus destroys or kills the host cell.

What is when the viruses burst from the cell at the end of the lytic cycle?

The virus that causes the disease AIDS.

What is HIV?

The disease caused by the adenovirus.

What is the common cold?

Deadly filovirus which causes symptoms such as high fever and uncontrollable bleeding.

What is Ebola?

A spherical virus transmitted through inhalation that is characterized by fever, chills, cough, sore throat, muscle aches, and fatigue and is often prevented through an annual vaccine.

What is influenza (flu)?

The type of cells that HIV attacks and the human body system these are a part of.

What are white blood cells (T-cells) that are part of the immune system?

A substance produced from “killed” or weakened pathogens.

What is a vaccine?

An organism that shelters and nourishes something, like a virus.

What is a host?

A virus that replicates by first transcribing its RNA into DNA.

What is a retrovirus?

The viral DNA segment of a bacteriophage that is inserted into a bacterium at the onset of the lysogenic cycle.

What is a provirus or prophage?

A viral protein molecule that causes disease in animals (such as mad cow disease).

What is a prion?

The first virus discovered.

What is TMV, Tobacco Mosaic Virus?

The scientist who discovered the first virus.

Who was Stanley?

The scientist who developed the first vaccine (for smallpox using cowpox).

Who is Jenner?

Two ways (of the 4) viruses are similar to living cells.

Virus & Cell Similarities 1. proteins 2. nucleic acid (DNA or RNA). 3 Virus & Cell Similarities 1. proteins 2. nucleic acid (DNA or RNA)? 3. can evolve/mutate 4. can have receptor/marker proteins

Properties of life that viruses do not have, so they are considered nonliving. (at least 3)

What are: 1. do not grow 2. do not metabolize 3 What are: 1. do not grow 2. do not metabolize 3. cannot maintain homeostasis 4. cannot reproduce on own?
