This table includes some types of DNA sequences observed in prokaryotic chromosomes (e.g. E. coli). Some of those sequences are common components of prokaryotic protein-coding genes (i.e. regions of a gene).
Use the numerals assigned to each type of DNA sequence to answer the parts below.

a. _3__: the region of DNA at which RNA holoenzyme untwists double-stranded DNA to form the open promoter complex.
b. _7__: the DNA sequence that first binds to the holoenzyme at the initiation of transcription.
c. _____: the first region, or part, of a gene to be transcribed.
d. _____: this region of the gene, when transcribed, will cause the process of transcription to end.
