Explain the process of replication of a retrovirus after it gains entry into the human body.

Explanation

### Step-by-Step Solution for the Replication of a Retrovirus

1. **Entry into the Host**: The retrovirus enters the human body, typically through bodily fluids. It attaches to the surface of a host cell, usually a T-helper cell, by binding to specific receptors.

**Hint**: Remember that retroviruses often target immune cells, which play a crucial role in the body's defense.

2. **Uncoating**: Once inside the host cell, the virus undergoes uncoating, where the viral envelope is removed, releasing the viral RNA and enzymes into the host cell's cytoplasm.
