If the viral genome results in spare capacity, viral packaging mechanisms may incorporate bacterial genetic material into the new virion. Alternatively, generalized transduction may occur via recombination. Generalized transduction is a rare event and occurs on the order of 1 phage in 11,000. [citation needed]
In physiology, transduction is the translation of arriving stimulus into an action potential by a sensory receptor. It begins when stimulus changes the membrane potential of a sensory receptor . A sensory receptor converts the energy in a stimulus into an electrical signal. [ 1 ]
Signal transduction is the process by which a chemical or physical signal is transmitted through a cell as a series of molecular events. Proteins responsible for detecting stimuli are generally termed receptors , although in some cases the term sensor is used. [ 1 ]
Visual phototransduction is the sensory transduction process of the visual system by which light is detected by photoreceptor cells (rods and cones) in the vertebrate retina.A photon is absorbed by a retinal chromophore (each bound to an opsin), which initiates a signal cascade through several intermediate cells, then through the retinal ganglion cells (RGCs) comprising the optic nerve.
Each signal transduction occurs with a primary extracellular messenger that binds to a transmembrane or nuclear receptor, initiating intracellular signals. The complex formed produces or releases second messengers that integrate and adapt the signal, amplifying it, by activating molecular targets, which in turn trigger effectors that will lead ...
Transduction (trans-+ -duc-+ -tion, "leading through or across") can refer to: Signal transduction , any process by which a biological cell converts one kind of signal or stimulus into another Olfactory transduction
Transduction in general is the transportation or transformation of something from one form, place, or concept to another. In psychology , transduction refers to reasoning from specific cases to general cases, typically employed by children during their development.
The significance of TGF-β is apparent with the human diseases that occur when TGF-β processes are disrupted, such as cancer, and skeletal, intestinal and cardiovascular diseases. [ 3 ] [ 4 ] TGF-β is pleiotropic and multifunctional, meaning they are able to act on a wide variety of cell types.
