Hello.
00:01
So let's answer now the problem.
00:02
So the problem is about a specific example of horizontal gene transfer.
00:15
So when we speak of horizontal gene transfer, it is the movement of genetic material.
00:32
Okay, so it is a movement of the genetic material from one organism to another organism.
00:50
And this another organism is not an offspring.
00:53
Okay, take note of that because if the transfer of genetic material is from an organism, okay, from an organism, which is from an organism, from one organism to another organism, and that another organism is an offspring, therefore, that is what we call a vertical gene transfer.
01:20
So when you speak of vertical gene transfer, the transfer is from parent to offspring.
01:25
But since here, the transfer, the transfer, the transfer is from the transfer is from one organism to another organism that is not an offspring therefore it is a horizontal gene transfer and horizontal gene transfer happens in bacteria we have three types okay the first type is the conjugation wherein in conjugation there is a cell to cell contact so that one bacteria can pass on the gene to another bacteria, cell -to -cell contact must happen.
02:14
So this is what we call conjugation.
02:16
And then we have also the term transformation wherein a cell adopts a naked dna.
02:36
So there is a naked dna in the environment and it is integrated into a cell.
02:41
That's what we call transformation...
