What Does transduction Mean
It is called transduction to the process that allows transform a class into a different signal . The concept is used in different ways depending on the context.
The so-called signal transduction , for example, is the process that leads a cell to respond to substances from the outside through signaling molecules , which are found inside or on the surface of the cell itself. Among the molecules involved in signal transduction are neurotransmitters and hormones that bind to certain proteins.
When passing from one molecule to another inside the cell, the signals generate a response such as cell destruction or multiplication. It is important to note that signal transduction is key to normal cell function: when cells have abnormal signaling molecules, they can turn cancerous .
The idea of transduction is also applied in genetics regarding the transfer of deoxyribonucleic acid ( DNA ) from one bacterium to another by the intervention of a virus . Similarly, we speak of transduction to refer to the introduction of exogenous DNA into a cell through a viral vector .
The sensory transduction , meanwhile, is performed when a sensory stimulus is converted into another different. In general, the notion is linked to the transformation of a physical stimulus into an action potential.
In the framework of literary criticism , transduction indicates the dynamic transmission of a work thanks to mechanisms such as parody, readaptation or intertextuality. The term was proposed by the Czech Lubomír Doležel in a 1986 article .
