Question

Why is clonal selection necessary for the adaptive immune response but not the innate immune response? Select True or False for each statement.
T/F The adaptive immune response uses receptors to recognize pathogens, and the innate immune response does not.
T/F There is more receptor diversity in the adaptive immune response than in the innate immune response.
T/F Cells in the innate immune response do not require activation, and those in the adaptive immune response do.
T/F Clonal selection is used for targeting pathogens, and the innate immune response is used only to stop blood flow from the wound.

Accepted Answer

Hi everyone. Let's look at the next problem. It says clonal selection is a process in which B and T cells are produced to respond to a specific infection. These lymphocytes have unique blank that a doubt allow them to identify specific pathogens. So when we think about um in the immune system, the region on these cells that recognizes specific pathogens and interacts with them and binds to them. What we're looking for is a receptor and receptors here as choice. See both B cells and T cells have receptors. Um when the B cell binds to an antigen, it's signaled to begin to divide and proliferate uh clones of itself. T cells also recognize specific pathogens and they do that with the aid of the MHC proteins. So as the MHC proteins on the surface of the cell prevent present foreign proteins. The T cell recognizes them with its receptor site. And also similar to the B cell is selected for to produce reproduce itself. So that process of recognition through the receptor site and then um division and proliferation of the cells that bind is clonal selection. So let's just go through our other answer choices. Choice A says antibodies. While antibodies are the proteins made by the immune cells in response to infection or in response to these foreign cells or materials. So that's not our answer. It is the receptors on the cell that bind to the antigens, antibodies are proteins that are made in response. Choice B is epic tops well the ePA tops is what the receptor is binding to the epitaph is the site on the antidote that is specifically recognized and bound to buy the receptor. So it's that matching puzzle piece on the antigen itself. But not our answer. And finally, Choice the nucleus. Hopefully we don't have trouble ruling that out. As that's that organ l the membrane bound organelles in the cell that contains the chromosomes. So uh not what we're looking for here. So again, clonal selection uh is the process by which B and T cells respond to a specific infection. And these lymphocytes have unique choice C receptors that allow them to identify specific pathogens. See you in the next video.
