There are two main strategies for the induction of transcription: a strong promoter is negatively controlled by a repressor protein and induction of transcription is effected by an inducer (a ligand that inactivates the repressor).
A transcription unit is a linear sequence of DNA that extends from a transcription start site to a transcription stop site (Figure 4). Figure 4. The promoter, a DNA sequence that lies upstream of the RNA coding region, serves as an indicator of where and in which direction transcription should proceed.The promoter is not actually transcribed; its role is purely regulatory.he terminator, a sequence of nucleotides at the end of the transcription unit, is transcribed along with the RNA coding region. The terminator serves as a speed bump of sorts; transcription stops only after this region has been transcribed.
