Transcription
Definition:
(n.) The act or process of transcribing, or copying; as, corruptions creep into books by repeated transcriptions.
(n.) A copy; a transcript.
(n.) An arrangement of a composition for some other instrument or voice than that for which it was originally written, as the translating of a song, a vocal or instrumental quartet, or even an orchestral work, into a piece for the piano; an adaptation; an arrangement; -- a name applied by modern composers for the piano to a more or less fanciful and ornate reproduction on their own instrument of a song or other piece not originally intended for it; as, Liszt's transcriptions of songs by Schubert.
Example Sentences:
(1) These lysates are comparable to those of Escherichia coli in transcriptional and translational fidelity and efficiency in response to a given template DNA.
(2) This induction is sensitive to actinomycin D but not to protein synthesis inhibitor puromycin, indicating an effect of estradiol at the transcriptional level, possibly mediated by the estrogen receptor.
