The viral envelope merges with the cell plasma membrane (middle) releasing the matrix shell and core (purple bullet-shaped structure containing the viral genome) into the cell. The viral RNA (yellow string-like structure in core) is converted into viral DNA (red string-like structure in core) by the enzyme.. Figure 12 - Different types of HIV test.
