Day 1 Evaluate Viruses (google form)

Particles made up of proteins, nucleic acids, and sometimes lipids that can only reproduce by infecting living cells are called--

• Bacteria
• lysogenic
• viruses
• capsids

Why do viruses cause humans to have symptoms such as the one shown in the image?

• A. Viruses are often inhaled, and when they reproduce, they line your airways causing excess mucus.
• B. Fever is the result of exocytosis of the viruses from the cell.
• C. Fever is a result of the DNA being altered in the animal’s cells.
• D. The virus produces mucus as a byproduct of replication.

MULTI-PART: PART A Which is true about both viruses and living cells?

• A. Viruses can replicate on their own, cells cannot.
• B. Cells can replicate on their own, viruses cannot.
• C. Cells contain genetic material and viruses do not.
• D. Both viruses and cells contain DNA and RNA.

PART B Which structure is present in all viruses regardless of their structure?

• A. Protein spikes
• B. Capsid
• C. Envelope
• D. Tail

An antiviral drug specifically modifies viral receptors on a host cell. How might this affect the viral reproductive cycle?

• It would help facilitate viral endocytosis.
• It would prevent viruses from attaching to the host cell.
• It would destroy the virus’s capsid.
• It would prevent exocytosis.

Oncoviruses (temperate virus)are a type of animal virus that can cause an abnormal, often excessive, growth of tissue, developing cancer. Which type of virus is likely to be an oncovirus?

• Lytic virus
• Bacteriophage virus
• Lysogenic virus
• Influenza virus

A cold sore (herpes simplex) re-emerges after a student goes through a very stressful time. Why might this happen?

• The virus has gone through lytic cycle and is going through exocytosis.
• Dormant viral genes from an infection caused by the lysogenic cycle are activated.
• Stress increases the chance of a virus entering a cell.
• The virus is replicating inside your cells in the lytic cycle.

MULTI-SELECT: Which of the following are effective ways to prevent the spread of a virus? SELECT THREE CORRECT ANSWERS.

• Antiviral drugs
• Vaccines
• Herd immunity
• Antibiotic drugs
• Non-viral treatment

SHORT CONSTRUCTED RESPONSE Explain how viruses reproduce and how this process differs from the way cells reproduce. Think about the information carefully. Then enter your response in the box provided.

TEXT ENTRY: In the ​ (a)   cycle, the host cell makes many copies of the viral RNA or DNA. The viral DNA enters the nucleus of the host cell in the ​ (b)   cycle.

• Lytic
• Lysogenic
• viral
