What are the 5 stages of HIV life cycle?
The seven stages of the HIV life cycle are: 1) binding, 2) fusion, 3) reverse transcription, 4) integration, 5) replication, 6) assembly, and 7) budding. To understand each stage in the HIV life cycle, it helps to first imagine what HIV looks like.
What is the life cycle of HIV virus?
The series of steps that HIV follows to multiply in the body. The process begins when HIV encounters a CD4 cell. The seven steps in the HIV life cycle are: 1) binding; 2) fusion; 3) reverse transcription; 4) integration; 5) replication; 6) assembly; and 7) budding.
What is HIV summary?
HIV (human immunodeficiency virus) is a virus that attacks the body’s immune system. If HIV is not treated, it can lead to AIDS (acquired immunodeficiency syndrome). There is currently no effective cure. Once people get HIV, they have it for life. But with proper medical care, HIV can be controlled.
What are the 4 stages of HIV?
Stages of HIV Infection
- Stages of Infection – (assuming no treatment)
- Stage 1: Infection.
- Stage 2: Asymptomatic.
- Stage 3: Symptomatic.
- Stage 4: AIDS/Progression of HIV to AIDS.

What happens to the capsid during the HIV replication cycle?
A capsid containing the virus’s genome and proteins then enters the cell. The shell of the capsid disintegrates and the HIV protein called reverse transcriptase transcribes the viral RNA into DNA.
How are CD4 cells involved in the HIV life cycle?
CD4 cells are a type of white blood cell that play a major role in protecting the body from infection. HIV uses the machinery of the CD4 cells to multiply and spread throughout the body. This process, which is carried out in seven steps or stages, is called the HIV life cycle.
How are drugs used in the HIV life cycle?
HIV medicines protect the immune system by blocking HIV at different stages of the HIV life cycle. HIV medicines are grouped into different drug classes according to how they fight HIV. Each class of drugs is designed to target a specific step in the HIV life cycle.
