How does a retrovirus infect a cell and reproduce itself?

Retroviruses infects a cell copying RNA into DNA through the use of enzyme reverse transcriptase, and uses the DNA copy to infect host cells

Explanation:

Retrovirus is a virus that is composed of RNA. They infect a host cell * by using enzyme reverse transcriptase to copy their RNA into DNA, thereby using the DNA copy to infect an host cell*.

The viral genetic material use the * metabolic machinery of host cell replicate it's nucleic acid and produce it's specific proteins*. This is because once the viral component enters a host cell, it becomes an intracellular components. Since it is carrying genetic message specifying the structure of the intact viron, the viral genetic constituent diverts the host's enzyme and ribosome from their normal cellular roles to manufacture many daughter viral particles. This means that hundrerds of progeny viruses may arise from a single viron that infects a host cell.

Answer:Retrovirus reproduces itself by using a host plant. They infect the host plant DNA, which makes the host plant to recreate itself over and over again.
