== <span style="color: #FFFFFF;">Remembering</span> == * '''Gene Expression''' β The process by which information from a gene is used to synthesize a functional gene product (like a protein). * '''Transcription Factor''' β A protein that binds to specific DNA sequences to control the rate of transcription (the "Switch"). * '''Promoter''' β The region of DNA where the cell's machinery "Lifts Off" to start reading a gene. * '''Enhancer''' β A DNA sequence that can be far away from a gene but "Loops Over" to boost its expression. * '''Operon''' β A group of genes that are regulated together as a single unit (common in bacteria). * '''RNA Interference (RNAi)''' β A biological process where RNA molecules inhibit gene expression by neutralizing targeted mRNA. * '''Repressor''' β A protein that binds to DNA to "Block" transcription (the "Brake"). * '''Inducer''' β A molecule that "Starts" gene expression by disabling a repressor. * '''Methylation''' β Adding a chemical "Cap" to DNA that usually silences a gene. </div> <div style="background-color: #006400; color: #FFFFFF; padding: 20px; border-radius: 8px; margin-bottom: 15px;">
