WebMay 31, 2024 · 1. Viruses are not considered alive because they cannot reproduce independently and are therefore not organisms. As to the answer to 'why' something arose in evolution is always the same: because at that moment in time this specific set of traits was able to function and create a lot of offspring (or copies). WebViruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. …

There are two kinds of recombination: self-recombination and recombination with host. Self recombination occurs when two closely related viral genomes recombine by homologous crossing over.

A virus needs a living host, such as a person, plant or animal. To spread, a virus gets into a host's body and then into the host's cells. Then it takes over the host cell's machinery, using it to make more of the virus. Diseases caused by viruses include: how is iritis diagnosedWebIn another case, viruses play a role in genetic exchange between bacteria. Bacterial viruses, or bacteriophages (sometimes just called “phages”) ordinarily attach themselves to bacterial cells and then inject their genetic material into the cells. Such viruses hijack bacteria, using bacterial cell components to generate new phage particles. highland park library tx
