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. WebViruses can reproduce only within a host cell. The parental virus (virion) gives rise to numerous progeny, usually genetically and structurally identical to the parent virus. The actions of the virus depend both on its destructive tendencies toward a specific host cell and on environmental conditions. In the vegetative cycle of viral infection, multiplication …
