Frage 15 von 30

1

In viral cell attachment, there are multiple steps. First, must bind to two receptors to get into the host cell. Once in the cell, the virus' turns RNA into DNA. The enzyme enables integration of viral DNA into cellular DNA. After this, the enzyme cleaves polypeptides into functional . Lastly, the virus from the cell wall and leaves to infect other cells.

Frage 17 von 30

1

Inhibitors of viral enzymes can be competitive or non-competitive. With competitive inhibitors, the inhibitor:

  • Prevent integrase from inserting viral DNA into cellular DNA.

  • Coats the outside of the cell, preventing the virus from budding out of the cell.

Frage 28 von 30

1

HIV most commonly attacks Helper T cells. This is is a problem because:
