5.7) HIV

Question 1

How is HIV replicated?

1.
2.
3.
4.
5.

Answer 1

1. Attachment proteins attach to receptors on T-helper cell
2. RNA enters the cell
3. Reverse transcriptase converts RNA to DNA
4. Viral proteins are produced
5. Viral particles are assembled and released into the cell

Answer 2

1. RNA converted into DNA using reverse transcriptase
2. Reject ‘messenger’ or ‘m’ before RNA
   DNA incorporated/inserted into (helper T cell)
3. DNA/chromosome/genome/nucleus;
   DNA transcribed into (HIV m)RNA
   Accept descriptions of transcription
   (HIV mRNA) translated into (new) HIV/viral proteins (for
   assembly into viral particles);
