Definition of Transduction – What it is, Meaning and Concept

It is called transduction to the process which enables transform one kind of signal into a different one. The concept is used in different ways depending on the context.

The call signal transduction, for example, is the process that leads to a cell to respond to outside substances via signaling molecules, which are found inside or on the surface of the cell itself. Among the molecules involved in signal transduction there are neurotransmitters Y hormones that bind to certain proteins.

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 become cancerous.

The idea of ​​transduction also applies in the genetics according to the deoxyribonucleic acid transfer (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 via a viral vector.

The sensory transductionMeanwhile, it is carried out when a sensory stimulus is converted into a different one. Usually the notion is linked to the transformation of a physical stimulus in action potential.

Within the framework of Literary criticism, the transduction signals 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 an article by 1986.
