Understanding the life cycle of the HIV virus is essential for understanding how the virus attacks the organism and how it weakens the immune system of humans.
Different steps of life cycle of HIV
Binding and Fusion – There are many identifying marks on the upper level of the organism’s cell. HIV viruses, some of them are tied with special identification marks and fuse with organisms cells.
Infections in the cells – After the virus is strengthened and combined with the cells, the virus of the virus enters the cell and the process of infection begins.
Reverse Transcription – There is a type of enzyme in the virus, which is called reverse transcriptase. This transforms genetic material of the enzyme virus, RNA into DNA.
Integration – DNA, converted by enzymes in this stage, is mixed with the DNA found in the human cells, to which later the genes of the virus can be read with the human genes.
Transcription – At the time of the transition of the infected cell, by reading the genes of the virus, a special type of mRNA is formed.
Translation – In this stage, a long protin is formed from the viral mRNA in the cell.
Assembling (Assembly, Budding) – Various proteins of the virus get together, creating a new virus. This new undeveloped virus starts to emerge from the cell as a bud.
Immature Virus – In this condition, the undeveloped virus exits from the cell.
Virus developed – this stage develops virulently throughout the stage. The developed virus can then infect a new cell, or spread HIV in another person. By having this cycle repeatedly, the virus seems to increase its number.
