How do killer T-cells destroy viruses? How are viruses involved in bacterial transduction? Why can't a virus reproduce on its own? How does the rabies virus reproduce? How are viruses similar to parasites? Which feature do viruses have in common with animal cells?
because viruses reproduce so quickly and so often, they can often change slightly. Sometimes, mistakes creep into their genetic instructions. These changes might alter the protein coat slightly, so one year's batch of vaccine might not be ...

, although some viruses use rna as the information carrier instead of dna. most animals have two copies of each chromosome. in contrast, plants may have more than two copies of several chromosomes, which usually arise from errors in the distribution of the chromosomes during cell reproduction. ...
Only with ΔSa_immob as high as −240 J/mol/K representing smaller viruses do more than 30% of the 1000 cells have bound virus at the human body temperature of 37 °C according to the model in Fig. 5b. This is shown in Fig. 5c where nearly all the cells have bound virus at ...
Genetic remnants of viruses that are naturally present in the human genome could affect the development of neurodegenerative diseases. Researchers at DZNE come to this conclusion on the basis of studies on cell cultures. They report on this in the journalNature Communications. In their view, such ...
A virus can’t replicate on its own. To do so, viruses must enter a host cell, where they unleash their replication tools — proteins called polymerases — to make copies of themselves. The current study focused on one such protein — a viral DNA polymerase — crucial for HSV’s ability...
nations does haverules. These rules, like the Geneva Conventions, for example, tend to discourage the wholesale destruction of civilians, and they govern the treatment of prisoners of war. The rules are not always followed to the letter, and many times are broken completely, but they do exist...
less common to humans. Humans are also driving deeper into previously uninhabited areas. Now that we’re living in closer proximity with animals, there’s a higher chance for humans to be infected for the first time while new viruses and parasites are mutating to unlock and i...
