b. conjugation.
c. mutation.
d. meiosis.

Accepted Answer

Hello everyone. And in today's video we're going to be talking about the main methods of gene exchange in bacteria. And so this term in bacteria is very important for us because as we can see we have an answer choice being de mayo sis um aosis does not occur in bacteria. It occurs in eukaryotic cells. So we can already see where this question is going still. Let's go over the main methods of gene exchange in bacteria. So we can recall starting with transfer transaction transaction is a method of gene exchange where a virus takes up DNA from one cell and transfers it to another. It is the medium by which these D. N. A. Or these genes are transferred. So it is a method of gene exchange and we can cancel it out from our answer choices. Then we have transformation, transformation is a process by which a cell is made competent by a certain process. And then it's able to accept these plasmids which are portions of DNA that contain genes. So it is also a type of change and we can cancel it out from our answer choices. Finally we have conjugation. Conjugation is a process by which to cells can directly exchange genes via a sex pilots. Which is a connection a physical connection that is created between the two cells where these plasmids are able to travel through it and basically be exchanged between the two cells. So it is also a type of genetic change. Now this all leaves us as we said with mayo sis which is a type of cell division in eukaryotic organisms that produces sex cells. It produces gametes which are essential for life and reproduction. And so this is not the type of gene exchange in bacteria, and we can highlight it as being our final answer. Thank you very much for sticking around until the end of this video. I really appreciate it and I hope to see you on the next one.
