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).
This is the machine that actually reads the DNA code and makes the RNA. Transcription factors that promote gene expression are called activators. Figure 1 shows transcription factors and RNA polymerase (RNAP) making an mRNA copy of the DNA. Interestingly, transcription factors can also prevent the transcription of a gene.
