  • Transcription Factors


    Proteins that bind to specific DNA sequences to regulate transcription initiation.

  • What is the role of general transcription factors?


    They are essential for the transcription of all genes and recruit RNA polymerase to the promoter region.

  • TATA Box


    A DNA sequence in the promoter region that recruits the transcription initiation complex (TIC).

  • What is the transcription initiation complex (TIC)?


    A complex of general transcription factors and RNA polymerase bound to the promoter region.

  • Specific Transcription Factors


    Proteins that bind to control elements to regulate the transcription of specific genes.

  • What are control elements?


    Regions of noncoding DNA where specific transcription factors bind.

  • Distal Control Elements


    Control elements located far from the promoter region; a group of these is called an enhancer.
