Document Summary
10:35 am refers to the processes within a cell that enable a gene to be expressed in specific cells and at. Structural gene: a segment of dna that doesn"t code for regulatory proteins, but codes for pr be used functionally or structurally throughout a cell or organism. The activity of structural genes is controlled by another gene called a . Regulatory gene: a segment of dna responsible for producing proteins that control the expre genes, switching them on and off as conditions require. An operon is a group of linked structural genes with a common promoter and operator, that single unit. Promoters are non-coding base sequences that signal the start of a gene. Rna polymerase bi promoter region of a gene to begin the transcription process. An operator is a short (non-coding) dna segment that provides a binding site for a repressor transcription of an operon.
