Transcription factors (article) | Khan Academy
https://www.khanacademy.org/science/ap-biology/gene-expression-and-regulation/regulation-of-gene-expression-and-cell-specialization/a/eukaryotic-transcription-factors
WEBGeneral, or basal, transcription factors simply assist in the binding of RNA polymerase to the promoter. Other types of transcription factors include activators and repressors. These transcription factors affect transcription in different ways; activators assist in the binding of RNA polymerase and repressors stop transcription.
