There has always been one big question in biology, and that is, are viruses living or not? Some biologists claim they are alive, whereas others defend that they are not alive. Although biologists who believe that viruses are alive may have some good points, there is just not enough evidence...
The section begins with a textbook statement: “‘They are not cells, they have no metabolism, and they are inert as long as they do not encounter a cell, so many people (including many scientists) conclude that viruses are not living,’ says Patrick Forterre, a microbiologist at the ...
Are viruses living organisms or not? Explain. Describe and explain the structure of bacteria. Give two examples, and list some diseases they cause. Describe the following briefly: What detrimental and beneficial effects can bacteria have on humans?
Whether or not viruses are alive remains unsettled. Discoveries of giant viruses with translational genes and large genomes have kept the debate active. Here, a fresh approach is introduced, based on the organisational definition of life from within systems biology. It views living as a circular ...

are not living things. Viruses are complicated assemblies of molecules, including proteins, nucleic acids, lipids, and carbohydrates, but on their own they can do nothing until they enter a living cell. Without cells, viruses would not be able to multiply. Therefore, viruses are not living ...
He made the ancient form of the MEQ gene and shoot it into living chicken cells. It did not turn on any of the genes associated with tumour formation. In comparison, a modern MEQ gene quickly showed its tendency to cause tumours.(为了验证这一假设,Fiddaman博士进行了一个大胆的实验。他制造...
More than a quadrillion quadrillion individual viruses exist on Earth, but most are not poised to hop into humans. Can we find the ones that are?
