Question

Diseases such as diphtheria result from a process called lysogenic conversion in which viral dna is integrated into a bacterial chromosome, which allows particular toxins to be expressed. what mechanism of gene transfer is involved?

Answer 1

The correct answer is horizontal gene transfer, transduction.  

Transduction (a type of horizontal gene transfer)is the process by which foreign DNA is introduced into a bacteria cell. When viruses infect bacterial cells, their DNA is integrated into a bacterial chromosome and thus harness the replicational, transcriptional, and translation machinery of the bacteria. As a result, bacteria cell makes numerous virions (viral particles).
