Where does translation collide?

The step of gene expression in which a ribosome reads the sequence of a messenger RNA, three bases at a time, and assembles the matching chain of amino acids into a protein: transfer RNAs bring each amino acid, and the genetic code sets which codon calls for which residue. Crick's 1970 Central dogma of molecular biology placed translation as the residue-by-residue transfer of sequence information from nucleic acid to protein, a flow that does not run in reverse. The referent is a molecular process inside a cell, counted in proteins made from a messenger, and it shares nothing with rendering a text into another language, shifting a shape across a plane, or moving a finding from the laboratory to the clinic.[1]

Unit

A protein assembled from a messenger RNA at the ribosome

Recovery means

Not applicable

Measured by

Followed by rates of protein synthesis, by ribosome profiling, and by reporter assays of the messenger being translated

The rendering of a text or an utterance from one language into another, so that a reader who does not know the source can receive its meaning: the translator chooses how closely to follow the wording and how far to naturalise it for the new audience, and those choices are the subject of translation studies. Venuti's 1995 The Translator's Invisibility traced how a fluent, domesticating style makes the translator disappear, and argued for reading translation as an interpretive act with its own history. The referent is an act of language and interpretation between human tongues, judged by fidelity and readability, not a chain of amino acids, a rigid motion in geometry, or the transfer of research into practice.[2]

Unit

A source text rendered into a target language

Recovery means

Not applicable

Measured by

Assessed by comparison with the source, by readers' judgements of fidelity and fluency, and by scholarly critique

A transformation of a space that moves every point by the same distance in the same direction, given by a single displacement vector: a translation slides a figure without turning it, resizing it, or reflecting it, so it is a rigid motion, or isometry, that preserves distances and angles. Coxeter's 1969 Introduction to Geometry presented translation among the isometries of the plane, composable with rotations and reflections to build up every rigid motion. The referent is an exact mathematical operation defined by a vector, with no measurement error and no flow of information, unlike a ribosome's synthesis of a protein, the rendering of a text between languages, or the move from bench to bedside.[3]

Unit

A displacement of every point by one fixed vector

Recovery means

Not applicable

Measured by

Given exactly by its displacement vector, and verified by checking that distances and orientation are preserved

The work of moving discoveries from basic science into treatments, tests, and practices that improve health, and back again as clinical questions reshape the laboratory: the term names a research enterprise and a funding priority built to close the gap between what is known at the bench and what reaches the bedside and the community. Woolf's 2008 The meaning of translational research and why it matters separated the step from laboratory science to human studies from the step from proven interventions into everyday care, and noted how loosely the word is used. The referent is a programme of applied research and its policy, judged by findings that reach patients, not a ribosome reading a messenger, a translated text, or a shift by a vector.[4]

Unit

A finding carried from basic research toward clinical use

Recovery means

Not applicable

Measured by

Tracked by how far discoveries progress along the research pipeline and reach approved, adopted care

In science and technology studies, translation refers to the process by which actors define roles, enrol others and come to speak for them, traced through scientists, scallops and fishermen. This meaning comes from Callon (1984) in The Sociological Review.[5]
