Answer:
2,1,3,4
Explanation:
HIV is the acronym for the human immunodeficiency virus. Aids-causing disease that attacks the immune system which is the system responsible for defending the body from disease. Infection of this virus at the cellular level occurs when it attacks the TCD4 + cell lymphocytes, after this attack the virus binds to the receptors of this cell, although not yet coded. With the binding of the virus in the cell, the virus envelope opens and releases the viral content within the host cell, after which viral RNA uses the reverse transcriptase enzyme to transcribe its DNA that migrates to the host cell nucleus with the entry. The viral DNA in the nucleus is linked to the cell DNA, reaching the pro-virus form of HIV. Now able to replicate itself, the virus begins transcribing its RNA and can reach 100 billion copies a day in an untreated individual. At this point, the virus uses the cellular apparatus to create the other structures necessary for the release of the virus into the extracellular medium. After this, the viral RNA created is assembled in its envelope and springs from the host cell, which may cause it to rupture.
With this, we can conclude that the correct sequence of the information exposed in the question are: 2,1,3,4.
TAC: Treatment Action Campaign
TAC is an organization in South Africa. It campaigns for the access of HIV/AIDS treatment for the people.
South Africa has been identified as one of the countries with the most number of people who are HIV/AIDS positive. Because of this, TAC initiated campaigns for access of HIV/AIDS treatments that will be funded by the government.
One of the achievement of TAC happened in 2002 when the Constitutional Court ruled that the South African government provide anti-retroviral drugs.
Anti-retroviral drugs are to be taken by pregnant women who are AIDS positive. These drugs are designed to prevent the transmission of AIDS from the mother to their babies during childbirth.
