The term transduction refers to representations of information which could not normally be perceived by the sensory system of human beings (say, by using different colors for showing a body’s emission of different degrees of warmth). Email. The most striking feature is the transfer of genetic material from cell to cell by viruses. Transduction is important because of its implications for scientific research and bacterial antibiotic resistance. Classically, transduction has been used when talking about natural language, such as in the field of linguistics. signal transduction control of cellular activity by way of an extracellular signal being transduced into an intracellular response. The donor is subjected to LYSIS, the recipient is infected with a transducing phage. Signal transduction is the process of transferring a signal throughout an organism, especially across or through a cell.Signal transduction relies on proteins known as receptors, which wait for a chemical, physical, or electrical signal.Chemical signals are called ligands, and can be produced by organisms to control their body or received from the environment. Transduction is a common tool used by molecular biologists to stably introduce a foreign gene into a host cell’s genome. During transfection, DNA is deliberately introduced into host cells while transduction is naturally performed by viruses. …virus particle is called a transducing phage because, when it infects a bacterial cell, it can transmit the gene captured by λ phage DNA into the next bacterial cell it infects. Generally, the conversion of one form of energy into another. a hormone) to an effector system to stimulate the appropriate cellular response.
