What else can I help you with?
Are viruses general or highly specific to the cells they can infect?
Highly specific
Why are most viruses highly specific to cells they infects?
viruses must bind precisely to proteins on the cell surface and than use a hosts genetic system, this is why most viruses are highly specific to the cells they infect
What are most viruses highly specific to the cells they infect?
somehow
What are the different theories on Viruse?
There are several theories explaining the origin and evolution of viruses, including the regressive hypothesis (viruses evolved from cellular organisms), the coevolution hypothesis (viruses and host cells evolved together), and the escape hypothesis (viruses once were cellular organisms that escaped from cells). The exact origins of viruses remain a topic of ongoing research and debate in the scientific community.
How did viruses come to be?
Viruses are thought to have evolved from ancient cellular organisms, possibly derived from genetic elements that "escaped" from cells. It is believed that viruses originated billions of years ago and have co-evolved with their hosts, adapting to exploit different cellular mechanisms for replication and survival.
Why are viruses effective as vectors?
Viruses have proven to be highly effective as vectors since these are biological entities with a natural function of infecting host cells.
Are viruses able to infect any cell?
Viruses are highly specific in their ability to infect host cells, as they typically target particular species or cell types based on the presence of specific receptors on the cell surface. Each virus has evolved to recognize and bind to these receptors, which limits its range of potential hosts. While some viruses can infect a wide variety of cells, most are specialized and can only infect certain types of cells within a specific organism or closely related species.
Why the humans are not affected by plant viruses?
Humans are not affected by plant viruses primarily because these viruses have evolved to infect plant cells, which have different cellular structures and biochemical pathways than human cells. Plant viruses typically rely on specific receptors and mechanisms found only in plant species, making it unlikely for them to successfully invade human cells. Additionally, the immune systems of humans are designed to recognize and combat a wide range of pathogens, including viruses, further protecting us from plant viruses.
Are viruses general or specific to the cells that they infect?
viruses are specific to the cells they infect called host cells
Is genetic material found in both cells and viruses?
Yes, both viruses and cells have DNA.
Are viruses made up of tissues?
No, tissues are made up of cells and viruses are not even cells.
Are viruses smaller than eukaryotic cells?
Yes, viruses are smaller than eukaryotic cells.
