Question
Answer
Enveloped virus   Wrap themselves in a bit of the plasma membrane of the host cell as they are released.  
🗑
Non-enveloped Virus   Enclosed only by a capsid.  
🗑
Viruses are not considered living because   they are dependent on their hosts metabolic machinery for replication.  
🗑
The _______ pandemic of 1918-1919 killed millions.   Influenza.  
🗑
Virus use in gene therapy step 1   Insert cloned gene into viral genome.  
🗑
Virus use in gene therapy step 2   Let virus infect bone marrow cells that have been removed from the patient and cultured.  
🗑
Virus use in gene therapy step 3   Viral DNA carrying the cloned gene inserts into the patients DNA.  
🗑
Virus use in gene therapy step 4   Inject engineered cells into patient.  
🗑
Virus Reproductive Cycle Step 1   After the virus bind to the host cell's membrane, the viral DNA is taken into the cell  
🗑
Virus Reproductive Cycle Step 2   Viral DNA is replicated into dozens of new copies, using the hosts metabolic machinery and energy.  
🗑
Virus Reproductive Cycle Step 3   Viral mRNA is transcribed from the Viral DNA.  
🗑
Virus Reproductive Cycle Step 4   New viral proteins are synthesized again using the host's proteins-production molecules.  
🗑
Virus Reproductive Cycle Step 5   The new viral DNA and proteins assemble, forming many new virus particles.  
🗑
All viruses have a container the _____ that holds their genetic material, and sometimes the capsid is wrapped in ______   Capsid, Membrane (envelope)  
🗑
Capsid   Container made of protein.  
🗑


   

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
 
To hide a column, click on the column name.
 
To hide the entire table, click on the "Hide All" button.
 
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
 
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
