HIV

 

1   When a retrovirus infects a cell the RNA has to be converted to
  A protein
  B DNA
  C lipids
  D steroids
  E carbohydrates
2   What viral proteins bind to receptors on CD4 cells
  A gp41
  B gp120
  C CXCR4
  D both gp41 and gp120
  E all of the above
3   How many different kinds of proteins are in an HIV particle?
  A 1
  B 2
  C 3
  D 4
  E 5
4   DNA Integration takes 
  A human DNA and inserts double stranded viral RNA
  B human DNA and inserts single stranded viral RNA
  C double stranded viral DNA and inserts sections of human DNA
  D human DNA and inserts double stranded viral DNA
  E human DNA and inserts single stranded viral DNA
5   Viral mRNA codes for the production of 
  A Envelope Proteins
  B Protease
  C A long, multiprotein strand
  D Only A & B
  E A , B & C
6   What is the role of protease?
  A To cut RNA
  B To cut DNA
  C To help the viron bud from the CD4 cell
  D To cut the protein strand into functional proteins (post translational modification)
  E To digest the RNAase-H
7   The target of enfuvirtide is
  A the binding of the virus with receptors on the CD4 cells
  B the protease
  C the RNAase
  D the core protein
  E the integrase
8   NRTI's work by 
  A interfering with the action of the protease
  B interfering with the action of the integrase
  C interfering with the action of the reverse transcriptase
  D interfering with the action of the RNAse-H
  E binding to the viral partially transcribed viral DNA
9   NNRTI's work by
  A interfering with the action of the protease
  B interfering with the action of the integrase
  C interfering with the action of the reverse transcriptase
  D interfering with the action of the RNAse-H
  E binding to the viral partially transcribed viral DNA
10   Protease inhibitors act
  A Outside the cell, blocking HIV fusion
  B Inside the cell, blocking reverse transcription
  C Inside the cell, blocking integration
  D Inside the cell, blocking budding
  E Outside the cell, blocking conversion of the long protein strand into functional proteins.

At most you can work in pairs (NO threes, fours, fives etc)! If you work in a pair, put both names in the box.
