Answer

Item from Fig. 18.8 -- Category in Fig. 21.6 Enhancer -- Regulatory sequences Proximal control elements -- Regulatory sequences Transcription start site -- Regulatory sequences/exon Exon -- Exons Intron -- Introns PolyA signal sequence -- Regulatory sequences Transcription termination region -- Regulatory sequences

Work Step by Step

See Ch. 18, including the text near Fig. 18.8 which describes the job of each part labelled at the top of Fig. 18.8. Most of the parts control transcription or RNA stability, making them regulatory sequences.
