Question

Match the characteristics of eukaryotic cells in column A with their functions in column B.

Accepted Answer

Hi, everybody. Here's our next problem which of the following structures allows bacteria to bind specific receptor structures and colonize specific surfaces. A Pli B, Fmri C flagella or D cell wall. So when we look at our answer, choices, three of these are a little bit trickier, they all involve filamentous sort of projections from the cell surface, pila FMRI and flagella. You should be able to rule out choice D cell wall pretty easily because we're talking about a specific structure allowing DNA to bind and colonize. We're looking for something that projects out from the cell wall. So how do we distinguish between these three? Well, flagella is perhaps the most well known um they project out and rotate around allowing the bacteria to move. So they provide motility as their main function. So that's not what we're looking for. So we're left with Pilla and FMRI, which are a little trickier to tell apart. But they both again, they have these sort of filamentous structures that go out. But the ones that allow colonization of surfaces are choice b the fem. So these are long filamentous polymeric protein structures. They're on the surface of the bacteria and binding these specific receptor surfaces, lets them form these biofilms in certain areas. For instance, mucous membranes inside the body. And, and in fact, this is so important that sometimes if you change the gene, if you mutate the gene, so they're not present, the bacteria actually aren't even dangerous because they can't colonize their usual spot choice. A the pila also project out from the cell walls but their role is in motility and then also sometimes connecting two cells to allow the transfer of genetic material such as plasmids. So that's not what we're looking for, but not the one we're looking for. So again, the structure that allows bacteria to bind to specific receptor structures and colonize specific surfaces is choice B fem E see you in the next video.
