WebViruses, on the other hand, are much smaller than bacteria and consist of a protein coat and genetic material, either DNA or RNA. They cannot replicate on their own and need to infect host cells to reproduce. Once inside a host cell, the virus uses the cell's machinery to make copies of itself, which can then infect other cells. WebJun 9, 2024 · Gaglia studies how viruses take control of infected cells and reprogram the cells’ machinery to reproduce themselves. “We’ve been working on a protein that the virus encodes that destroys the host RNA, blocking the cells from being able to express their own protein and blocking, among other things, antiviral response,” she says.

WebColor the capsid (C) green and the DNA (D) blue and the tegument (E) purple. DNA released into the cell integrates with the cell’s DNA. From there, the virus controls the cell and makes the cell produce more virus particles. When the process is completed, the cell will release the new viruses which will then infect other cells.
