"WebGenetic recombination is the exchange of part of genome between two genetic entities. 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. This happens for DNA viruses and is very common in prokaryotic viruses.

WebA virus is a tiny, infectious particle that can reproduce only by infecting a host cell. Viruses "commandeer" the host cell and use its resources to make more viruses, basically reprogramming it to become a virus factory.

WebViruses are continuously changing as a result of genetic selection. They undergo subtle genetic changes through mutation and major genetic changes through recombination. Mutation occurs when an error is incorporated in the viral genome. Recombination occurs when coinfecting viruses exchange genetic information, creating a novel virus. 2 WebIn conjugation, genetic material is exchanged during a temporary union between two cells, which may entail the transfer of a plasmid or transposon. In transduction, DNA is transmitted from one cell to another via a bacteriophage.

WebFeb 4, 2024 · Viruses are bits of genetic information, either RNA or DNA, surrounded by protein. A virus needs a living host, such as a person, plant or animal.
