Overview
Regulatory proteins play a crucial role in the process of transcription, which is the first step in gene expression. These proteins, including transcription factors, enhancers, and silencers, interact with DNA to either promote or inhibit the transcription of specific genes. Understanding how these ...
Key Terms
Example: During transcription, the gene is transcribed into messenger RNA (mRNA).
Example: RNA polymerase binds to the promoter region to start transcription.
Example: The transcription factor binds to the promoter to initiate transcription.
Example: Enhancers can be located far from the gene they regulate.
Example: Silencers can prevent the binding of transcription factors.
Example: Gene expression can be influenced by regulatory proteins.
