Document Summary
We will now begin talking about signals which can tell the cell which genes need to be active and which genes need to be silenced. These experiments focus more on a protein-chemistry view, whereas the previous section focused on the mrna and dna aspect of the mechanisms. Dr. schock: effector proteins could also shut down the receptor in a feedback loop. Signal transduction is an ancient process; it can be found in every type of cell (from bacteria to humans and plants) In bacteria, exchange of dna can be carried out signal transduction, often involved in regulation population density of a bacterial colony. Signal transduction can be divided into certain classes depending on various factors. Developmental transduction mechanisms: this can be seen in developments from the fertilization of an egg to an adult, in which various genes are turned on and off sequentially, during pregnancy, the female body is.
