Bacteria are living organisms that can reproduce independently, while viruses are non-living entities that require a host cell to replicate. Bacteria are larger, have complex structures, and can ...

Even single cell organisms like bacteria can reproduce independently on surfaces outside the body, but viruses can only survive for a while outside host cells.

Viruses are extremely adaptable but they have a problem: They cannot reproduce, so they smuggle their genes into suitable host cells.

Viruses consist only of a DNA or RNA genome wrapped in a protein coat, and they must infiltrate into cells in order to reproduce. Having invaded a suitable cell, a virus essentially reprograms it ...

One such machinery is the viruses’ lack of ability to produce their own energy. To get the energy they need to complete replication, they hijack the host’s energy supply to reproduce within ...

Much is known about flu viruses, but little is understood about how they reproduce inside human host cells, spreading infection. Now, a research team has identified a mechanism by which influenza ...
