Bacterial conjugation is the transfer of genetic material between bacterial cells by direct cell-to-cell contact or by a bridge-like connection between two cells.[1] Discovered in 1946 by Joshua Lederberg and Edward Tatum,[2] conjugation is a mechanism of horizontal gene transfer as are transformation and transduction although these two other mechanisms do not involve cell-to-cell contact.[3]
Bacterial conjugation is often regarded as the bacterial equivalent of sexual reproduction or mating since it involves the exchange of genetic material. During conjugation the donor cell provides a conjugative or mobilizable genetic element that is most often a plasmid or transposon.[4][5] Most conjugative plasmids have systems ensuring that the recipient cell does not already contain a similar element.
The genetic information transferred is often beneficial to the recipient. Benefits may include antibiotic resistance, xenobiotic tolerance or the ability to use new metabolites.[6] Such beneficial plasmids may be considered bacterial endosymbionts. Other elements, however, may be viewed as bacterial parasites and conjugation as a mechanism evolved by them to allow for their spread. Source of the article published in description is Wikipedia.

I was having trouble understanding conjugation and this cleared up my confusion. Thanks!
You're welcome. Glad to hear that you're getting benefit from my lectures
Its always an Indian that is explaining Chemistry or Biology to me. HAHA thank you! I learned a lot
They're the best
Wow, I was not learning very much in my microbiology class but you explained this extremely well. Thank you!
You're welcome
Encyclopedia of biology 👍📚
Thank you so much for appreciating my efforts
Sir, you are really a great teacher. This video was very helpful.
Good video, cleared things up.
Thank you
Many thanks for a comprehensive explanation. Best wishes
Thank you. Glad it helped
Continuing your lectures
Am from Dubai
You're welcome
thanks shomu !! it was helpful.
Very helpful! Thank you!
better than my uni lecturer lol
Thank you
Plz share a vedio regarding structure of f plasmid
indian are good in science, salute your country :-)
+Ira Poklan thank you. Which country u are from?
Malaysia :-)
saving me from crying because my textbook is shit yet again! Thank you!
thank you
Thanks
I'm pretty sure the pilis does not work as a tunnel, though it is involved in conjugation
Gustavo Pinheiro Well isn't it the medium by which the genetic material gets transferred? The tunnel sort of makes sense as it is the means by which the genetic material goes to the recipient.
zbrdast lctr thanks
in case of f prime formation both chromosomal bacterial DNA and plasmid DNA are present on both DNA so both of DNA have transfer capability?
Yes it doesn't mean that they will always do conjugation for plasmid.....some time they transfer or exchange other material also through conjugation tube.
Bhaiya HRF is formed only in same bacteria or it can be formed from onther bacteria of same genera plz 🙏🙏🙏🙏🙏🙏 reply bhaiya
Connection between bacteria of same generation
@@shomusbiologyofficial it means it can formed on one bacteria as well as between two bacteria with same generation?
bad one.......expecting a lot more.....thnk u
+cafe unplugged please watch new lecture on horizontal gene transfer
Pretty decent video until the last minute, which was complete garbage.
Very helpful. Thank you!
