Cells can infect specific host viruses.
|

Viruses can infect certain cells.

Detailed explanation-1: -In conclusion, we can deduce that the statement which best relates cells and viruses is that viruses are capable of infecting certain cells. Explanation: Viruses main purpose is to infect cells.
Detailed explanation-2: -Which best relates cells and viruses? Viruses can infect certain cells. Which characteristic is most likely to be found in a mushroom but not in Thermus aquaticus shown above?
Detailed explanation-3: -A virus attaches to a specific receptor site on the host cell membrane through attachment proteins in the capsid or via glycoproteins embedded in the viral envelope. The specificity of this interaction determines the host-and the cells within the host-that can be infected by a particular virus.
Detailed explanation-4: -All types of cells have viruses that can infect them. Viruses have been discovered that are able to infect every different cell type, although not all viruses can infect all cell types. For example, bacteriophages are viruses that specifically infect bacterial cells.
Detailed explanation-5: -Plant and animal viruses enter through endocytosis, a process in which the cell membrane forms a pocket around the virus. Bacterial viruses, or bacteriophages, simply inject their genetic material into the cell. Next, the virus replicates, or reproduces, by hijacking the host cell’s machinery.
