In this video, we're going to begin our introduction to conjugation. And so first recall from our previous lesson videos that conjugation is one of the 3 main types of horizontal gene transfer. Conjugation is really just the direct transfer of DNA between 2 bacterial cells that are making direct cell-to-cell contact. Conjugation is going to require both a donor cell that will be donating the DNA and a recipient cell that will be receiving the DNA from the donor cell. Conjugation can either transfer a plasmid or it could transfer part of the donor cell's chromosomal DNA.
Now, there are 3 main types of conjugation that we have numbered down below: 1, 2, and 3. The first main type of conjugation is going to be F+ plasmid conjugation. The second main type of conjugation is going to be HFR cell conjugation. The third main type of conjugation is going to be F' plasmid conjugation where this little apostrophe here is stated as 'prime'. So, this is F' conjugation.
As we move forward in our course, we're going to talk about each of these three main types of conjugation in more detail in their own separate videos. But for now, notice that we're showing you an image or a map of our lesson on these three main types of conjugation. On the far left, once again, we have F+ plasmid conjugation, in the middle, we have HFR cell conjugation, and on the far right, we have F' cell conjugation. Within here, we give you some details of each of these different types of conjugation.
But once again, we're gonna talk more about each of these different types of conjugation as we move forward in their own separate videos. So, you don't really need to worry too much about the details that you see here right now. You can always come back and review this image after we've covered those more in-depth videos. What you'll notice about F+ plasmid conjugation, one of the main features that we're going to emphasize as we move forward as well, is that the entire F plasmid is going to be transferred from the donor cell to the recipient cell. With HFR cell conjugation, what we'll see is that only some or only part of the integrated F plasmid is going to be transferred, along with some of the donor cell's chromosomal DNA.
And once again, we'll be able to talk more about HFR cell conjugation later in our course. And then, last but not least, over here on the far right, what we have is F' cell conjugation. In this one, what we see is that, once again, the entire F' plasmid, with integrated donor DNA is going to be transferred. And once again, we'll be able to talk more about F' cell conjugation later in our course in a different video.
But for now, this here concludes our brief introduction to conjugation and the 3 main types of conjugation, and we'll get to learn more about these 3 main types of conjugation as we move forward in our course. So I'll see you all in our next video.
