WebMar 5, 2024 · Viruses are not made of cells. They are basically DNA inside a protein coat. To reproduce, a virus must insert its own genetic material into a cell (such as a bacterium). Then it uses the cell’s machinery to make more viruses. The researchers used different radioactive elements to label the DNA and proteins in viruses. This allowed them to ... WebThere are three mechanisms by which prokaryotes can exchange DNA. In (a) transformation, the cell takes up prokaryotic DNA directly from the environment.

WebFeb 4, 2024 · Viruses are bits of genetic information, either RNA or DNA, surrounded by protein. A virus needs a living host, such as a person, plant or animal. To spread, a virus gets into a host's body and then into the host's cells. Then it takes over the host cell's machinery, using it to make more of the virus.
