HIV STRUCTURE + replication

Question 1

what is the membrane?

Answer 1

= lipid membranes

Question 2

What do the attachement proteins do?

Answer 2

= bind to t-helper cells

Question 3

What does reverse transcriptase do?

Answer 3

= enzyme converts HIV RNA into HIV DNA

Question 4

What is the first step of HIV replication?

Answer 4

= HIV enters bloodstream
= binds to CD4 receptor on t-helper cells
=

Question 5

What is the second step of HIV replication?

Answer 5

= capsid fuses with t-helper cells membrane and RNA + reverse transcriptase enters
= reverse transcriptase catalyses the conversion of HIV rna to HIV dna

Question 6

What is the third step?

Answer 6

= HIV DNA enters the nucleus and is inserted into the host cells DNA
= mrna is created used to produce HIV molecules
= produces viral protein
= virus assembled and released from the cell

Question 7

What is the last step?

Answer 7

= HIV molecule breaks away from the cell membrane with part of the cell membrane forming phospholipid envelope
