The virus that incorporates its DNA into the host's genome is best described as a lysogenic infection. This is in contrast to lytic infection, where the virus causes the cell to lyse and release new virions. Option 4 is the correct option.
The virus you described in the lab, which infects humans and incorporates its genetic material into the host's genome, is best described as a lysogenic infection. During a lysogenic cycle, a virus integrates its DNA into the DNA of the host cell, where the viral DNA, known as a prophage when referring to bacteriophages, is replicated along with the host cell's DNA. This can lead to a long-term association between the virus and the host, where the viral genome is passed on during cell division, sometimes without immediately producing new virus particles. It contrasts with the lytic cycle, where a virus replicates inside a host cell and then causes the host cell to burst (lyse), releasing new virions. This information aligns with the thematic content provided, which describes both productive and lysogenic cycles, as well as transduction, the process where a virus can transfer genetic material between cells. Option 4 is the correct option.
The appropriate question is:
You discover a virus in the lab that infects humans and incorporates its genetic material into the host's genome. after further investigation, you discover that the genetic material of the virus consists of DNA. Which answer best describes this virus? group of answer choices
1) transposable infection
2) lytic infection
3) productive infection
4) lysogenic infection
