Read the following statements and choose the correct option 1. After entering the body, HIV uses the enzyme reverse transcriptase to convert its RNA genome into viral DNA inside macrophages. 2. The viral DNA gets incorporated into the host cell's DNA, directing the infected cells to produce virus particles. 3. HIV attacks helper T-lymphocytes, causing a progressive decrease in their number and weakening the immune sy

Step-by-step solution

After getting into the body of the person, the virus enters into macrophages where RNA genome of the virus replicates to form viral DNA with the help of the enzyme reverse transcriptase. This viral DNA gets incorporated into host cell’s DNA and directs the infected cells to produce virus particles (Figure 7.6). The macrophages continue to produce virus and in this way acts like a HIV factory. Simultaneously, HIV enters into helper T-lymphocytes (TH ), replicates and produce progeny viruses. The progeny viruses rele
