Overview
Transcription control is a fundamental aspect of molecular biology that determines how genes are expressed in cells. It involves various mechanisms, including the roles of promoters, enhancers, and transcription factors, which work together to regulate the transcription of DNA into RNA. Understandin...
Key Terms
Example: During transcription, the gene is converted into messenger RNA (mRNA).
Example: Gene regulation ensures that genes are expressed at the right time and place.
Example: The TATA box is a common promoter found in many genes.
Example: Enhancers can be located far from the gene they regulate.
Example: The protein p53 is a transcription factor involved in cell cycle regulation.
Example: RNA polymerase binds to the promoter to start transcription.
