Question

Explain the importance of the following features in conjugating donor bacteria:

homologous recombination

Accepted Answer

Hello, everyone and welcome to today's video. So through the process, a harmless bacterium is going to receive and incorporate DNA material into its chromosome from another pathogenic bacterium via horizontal gene transfer. And it too may become pathogenic. That's answer choice. A we have homologous recombination. As answer choice B we have crossing over as answer choice C we have binary fission and as answer choice D we have none of these. Let's begin by reviewing by reviewing answer choice B crossing over. Well, remember that crossing over is a process that is going to occur in meiosis and it involves the exchange of genetic material between two homologous chromosomes. However, also remember that this is going to be within a single organism. The question speaks about the transfer of genetic material between a harmless bacterium and a pathogenic bacterium. So crossing over is therefore incorrect and we're going to cancel it out. Then we have c binary fission. Now, binary fission is a process of asexuals reproduction in which a single organism is going to split into two identical daughter cells. Now, while it is true that it could inherit this pathogenic ability from the parent bacterium. This is not going to be a horizontal type of gene transfer. This is going to be vertical and therefore we're going to be cancel answer choice c binary efficient out. Finally, we have a homologous recombination. Well, remember that doing the homologous recombination is a process by which DNA from one organism is transferred to another organism. And the recipient organism can become pathogenic if the DNA transfer contains gene that confer pathogenicity. So the key here is that it's going to be a transfer of genetic information between organisms. Now, depending on what DNA or type of DNA is transfer, this organism may become pathogenic or not. Therefore, this is going to fit what the question is stating and we're going to use it to fill in this blank. The four answer choice, a homologous recombination is going to be the correct answer to this question. I really hope this video helped you and I hope to see you on the next one.
