Overview
Transcriptional regulation is a fundamental process that controls gene expression, allowing cells to respond to their environment and differentiate into various cell types. It involves various mechanisms, including the action of transcription factors, enhancers, and silencers, which work together to...
Key Terms
Example: The expression of the insulin gene is crucial for glucose metabolism.
Example: The transcription factor NF-kB is involved in immune response.
Example: Enhancers can be located far from the gene they regulate.
Example: Silencers help control the timing of gene expression.
Example: Splicing removes introns from pre-mRNA.
Example: Stable mRNA leads to higher protein synthesis.
