Transcription factors are proteins that influence the process of transcription.
Fig. 1 shows one mechanism of action.
Fig. 1
Identify region X and enzyme Y.
Stage 1 in Fig. 1 shows the transcription factor binding to region X which then results in stages 2 and 3 occurring.
Describe the events that take place during stages 2 and 3 of Fig. 1.
The transcription factor shown in Fig. 1 is a protein.
Suggest and explain how a mutation in the gene that codes for the transcription factor might affect the expression of the gene shown in Fig. 1.
The transcription factor shown in Fig. 1 is an example of an activator, which means that it initiates transcription or increases the rate of transcription.
Explain how a transcription factor might have the opposite effect and function as a repressor.
