Hello everyone.
00:01
In this question we have been given a signal pathway.
00:05
So here we have been said that the mov1 is important for the regulatory production of the arp protein.
00:16
So the binding of the mov1 to rec1 leads to the activation of ras, which basically means the activation of the cell growth.
00:29
So here this is a ras activates the protein kinase that leads to the activation of the regulatory protein that only binds to dna when activated by the protein kinase whose basically work is to phosphorylate the protein.
00:48
So the binding of the gene regulatory protein to the arp gene results in the transcription of the arp gene and the arp protein is required in cytosol and promotes the actin polymerization.
01:06
So here we can see that in the diagram there is rec one receptor present on the plasma membrane and to this the mov1 is attached.
01:21
So here mov1 is acting like the ligand of the rec one receptor and now now this here is activating the ras and now this pathway is taking place.
01:36
So here we have been asked that which of the following statement below is consistent with the change in behavior you would expect if you were to add mob1 to cells.
01:48
So here option a says that there will be more aftin filament in cells that have mo -1 compared to cells that did not have the mo -1 so here basically this arp protein is helping in the nucleation of the actin.
02:07
That means here the actin will form into the g actin that is the monomer here will form into the f actin here.
02:19
The nucleation has started taking place.
02:22
So that is true...
