Overview
Gene expression control is a fundamental concept in biology that determines how genes are turned on or off, influencing cellular functions and organismal traits. It involves complex processes such as transcription and translation, where DNA is converted into RNA and then into proteins. Regulatory el...
Key Terms
Example: The BRCA1 gene is linked to breast cancer.
Example: During transcription, the gene is converted into messenger RNA (mRNA).
Example: Ribosomes facilitate the translation of mRNA into amino acids.
Example: RNA polymerase binds to the promoter region to start transcription.
Example: The promoter region is where RNA polymerase attaches to begin transcription.
Example: Enhancers can be located far from the gene they regulate.
