Q
State the structure of a transcription unit
A
Structure gene: Gene being transcripted
Promoter sequence: Recognised by transcription factors (protein) and then
guide RNA polymerase to attach to gene
Termination sequence: Ends
the transcription process
Regulatory genes: Tells a cell when, where and under what condition to transcribe information, and how much mRNA has to be transcripted
Transcription factors: Bind to regulatory and other parts of the gene that regulate protein synthesis
