Transcription Transcription of DNA into RNA DNA transcription produces a single-stranded RNA molecule that is complementary to one strand of DNA.
Discovered in the bacterium, E. coli Used as a model for gene regulation An operon is a set of genes and the switches that control the expression.
OPERONS Chapter 18 Campbell and Reece. E. Coli synthesizes tryptophan 5 genes clustered together each reaction in pathway catalyzed by specific enzyme.
Control Mechanisms (Prokaryote) SBI4U. Controlling Expression When a gene is being used by a cell, it gets transcribed, and then the mRNA is translated.
