Answer:
The correct answer is: recognise specific regulatory sequence (of the gene) bound to specific transcription factors.
Explanation:
- A Gene is composed of the following regions:
- Protein coding region: This region gets transcribed by the RNA (Ribonucleic Acid) polymerase and translated into the proteins by the Ribosome.
- Regulatory sequences which includes:
- Promoter (TATA box): The process of transcription begins from this location. They have high concentration of Thymine and Adenine nucleotides.
- Terminator: The process of transcription ends here.
- Upstream Proximal Promoter Elements: They are located upstream of the transcription start site and are responsible for binding to various transcription factors that regulate (increase or decrease) the rate of transcription.
- Upstream Distal Promoter Elements: They can be located few kilo base-pairs upstream of the transcription start site of the gene. Binding of transcription factors to them can signal the chromatin-remodelling complexes to promote decondenstion of the region of the chromatin where the gene that needs to be transcribed is located.
