WebJun 9, 2024 · Viruses can have genomes based on DNA or RNA—unlike human genomes, which are made up of DNA, which then can create RNA. Gaglia studies how viruses take control of infected cells and reprogram the cells’ machinery to reproduce themselves. 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. the others wiki

WebFeb 4, 1999 · When two different strains of a virus infect the same host cell, their genetic material can mix and produce a new, recombinant strain. The animation illustrates an example of this process using the influenza virus. … WebIn 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.
