Transcription is the process of copying a segment of DNA into RNA for the purpose of gene expression. Some segments of DNA are transcribed into RNA molecules that can encode proteins, called messenger RNA (mRNA). Other segments of DNA are transcribed into RNA molecules called non-coding RNAs (ncRNAs).
Transcription (linguistics), the representations of speech or signing in written form Orthographic transcription, a transcription method that employs the standard spelling system of each target language; Phonetic transcription, the representation of specific speech sounds or sign components; service and software
A transcription service is a business service that converts speech (either live or recorded) into a written or electronic text document. Transcription services are often provided for business, legal, or medical purposes. The most common type of transcription is from a spoken-language source into text.
Transcription should not be confused with translation, which means representing the meaning of text from a source-language in a target language, (e.g. Los Angeles (from source-language Spanish) means The Angels in the target language English); or with transliteration, which means representing the spelling of a text from one script to another.
The power of transcription factors resides in their ability to activate and/or repress wide repertoires of downstream target genes. The fact that these transcription factors work in a combinatorial fashion means that only a small subset of an organism's genome encodes transcription factors.
Transcription and transposition errors are found everywhere, even in professional articles in newspapers or books. They can be missed by editors quite easily, just as they can be created quite easily. The most obvious cure for the errors is for the user to watch the screen when they type, and to proofread.
Transcription of this nature involves scale degree recognition and harmonic analysis, both of which the transcriber will need relative or perfect pitch to perform. In popular music and rock, there are two forms of transcription. Individual performers copy a note-for-note guitar solo or other melodic line.
Medical transcription, also known as MT, is an allied health profession dealing with the process of transcribing voice-recorded medical reports that are dictated by physicians, nurses and other healthcare practitioners. Medical reports can be voice files, notes taken during a lecture, or other spoken material.
