WebMay 18, 2024 · A promoter is a DNA sequence onto which the transcription machinery binds and initiates transcription. In most cases, promoters exist upstream of the genes they regulate. The specific sequence of a promoter is very important because it determines whether the corresponding gene is transcribed all the time, some of the time, or … WebAbstract. As a novice qualitative researcher, the author had little idea of the significant and vital role of transcription in the qualitative research process until she undertook her own transcription tasks. The questions she asked herself during that work led her to insights on transcription both as product and as methodological process.
