REPLICATION

• PROCESS OF HIV REPLICATION?

  1. HIV transported in blood until it attaches to a CD4 protein on T helper cells
  2. HIV protein capsule fuses with T helper cell membrane allowing RNA and enzymes from HIV to enter
  3. HIV reverse transcriptase enzyme copies viral RNA into a DNA copy and moves to T helper cell nucleus
  4. Here, mRNA is transcribed
  5. T helper cell creates viral proteins leading to new viral particles
• WHY IS HIV A RETROVIRUS?
