| 释义 | transduction noun[ U ] uk /ˌtrænzˈdʌk.ʃən/ us /ˌtrænzˈdʌk.ʃən/ transductionnoun[U] (OF CELLS)biology specialized the process of moving genetic material (= part of the DNA in cells) from one cell or bacterium to another using a virus: 转导 Transduction gives researchers a tool to genetically change bacteria.转导为研究人员提供了一个在基因层面上改变细菌的工具。 See also co-transduction His discovery of transduction in bacterial genes opened up the possibility of genetic engineering. The technique of using viruses to transfer DNA into bacteria, called "transduction", had not previously been used with streptomyces. Transduction seems to involve fragments of DNA too small to be of serious ecological importance. Gene transduction with these retroviral agents is essentially restricted to dividing cells. Genetics accession number adenine anaphase autosomal autosomally genetic fingerprinting genetically genetically engineered geneticist genic genomic genomics monozygotic mutate non-Darwinian non-familial non-genetic non-mutant nondominant sex-linked transductionnoun[U] (OF ENERGY)physics specialized the act of changing energy from one form to another: 转换 the transduction of physical wave to mechanical impulse or electrical signal物理波向机械脉冲或电信号的传换。 Vision is based on the transduction of light stimuli received through the eyes. Related word transduce Transduction is the basic concept behind voice transmission and refers to the conversion of energy from one form into another. Physics: energy, force & power animal magnetism anti-gravity atmospheric pressure attract attraction ballistic entropic entropically equilibrant erg excited geothermal inertia preatomic propulsive radiant energy self-propulsion sine curve the sound barrier thermodynamics Examples of transductiontransduction This skewing is evident with cytokines and immune effectors, cytokine receptors and signal transduction molecules. Sensation is the transduction of ambient energy (whether electromagnetic, kinetic, or chemical potential) into a spatiotemporal pattern of neural activity. However, no specific transducing molecules or transduction cascades have yet been identified in desmids. Both ex vivo and in vivo transduction approaches have been used. The signal transduction role of reactive oxygen species needs to be evaluated in the context of pregnancy. A suite of these signal transduction elements amplifies and integrates the hormone signal. In crayfish receptors, these functions appear to be proper ties of the transduction mechanism. However, this signal transduction has to be negatively regulated for homeostasis. The main limitations in treating metastatic disease include poor vector transduction efficiencies and difficulties in targeting remote tumour cells with systemic vector delivery. Nonviral vector systems have low transfection efficiencies, and most of the viral systems have the problems of poor tumour targeting, immunogenicity and low transduction efficiencies. Adaptations of receptor-couples signal transduction pathways underlying stress- and drug-induced neural plasticity. The 'coalescence' model of signal transduction can be illustrated by immune cell signalling. Note that the same needs not be true for restricted classes of tree transductions, because our representation is more flexible. Schaeffer, in his first statements, gave priority to the masking of the cause by the effect of the transduction. Firstly, the processing techniques used include finite-state transduction, finite-state word segmentation coupled with a morpheme-level grammar, and implementations of theories of lexical inheritance.
