Accepted Answer

Hi, everyone and welcome. Our next question says which type of transduction transfers only certain bacterial genes. A generalized transduction B transformation transaction, C conjugation, transduction or D specialized transaction. Well, first of all, we need to recall that transduction is the transfer of genetic material into a cell by means of a viral vector. So it uses a virus to transfer genetic material from one cell to another. So only two of our answers actually are types of transduction and that is a generalized transduction and D specialized transduction. Choices B and C are forms of genetic transfer but they're not transduction. So choice B transformation is the uptake of naked DNA, just DNA by itself by a bacterial cell. And then choice C conjugation again, not a form of transduction. It's when you have a physical joining of two bacterial cells by a pylos and you actually then have genetic material passing through this physical connection between them, specifically a temporary visible connection between bacterial cells. So B and C are out because they're not forms of transduction. So now we've got our two generalized and specialized. Well, we kind of can use the logic of the vocabulary itself, we're looking for only certain bacterial cells or only specific bacterial cells. So that leads us to specialized rather than generalized. And that is our answer, it's specialized transduction that we're looking for. It occurs when the phage that infects the donor cell. The page's DNA gets incorporated into the bacterial DNA and then it gets excised sometimes bringing along some neighboring bacterial genes with it, but only the genes that would be a adjacent to where the phage DNA integrated. And that excise genetic material is packaged into a new transduction particle. When it goes on to inject that material into the recipient cell, both page and bacterial DNA are transferred to the recipient cell. But again, not any bacterial DNA, just that bacterial DNA adjacent to where the page integrated into the chromosome. When we look at choice a generalized transduction, this is a process by which some of the bacterial chromosome gets accidentally packaged into a transduction particle. And it is only bacterial DNA and it can be any part of the bacterial DNA. All parts are equally likely to be transferred in generalized transduction. Thus, that general name. So again, that generalized transduction, the difference is it's not specific genes, it's any part of bacterial chromosome and only bacterial DNA rather than page plus bacterial DNA. So choice a, not the correct descriptor because we're looking for the type of transduction that transfers only certain bacterial genes. And that is choice d specialized transduction. See you in the next video.
