Enzyme necessary for transcription
WebThe trp operon, found in E. coli bacteria, is a group of genes that encode biosynthetic enzymes for the amino acid tryptophan. The trp operon is expressed (turned "on") when tryptophan levels are low and repressed (turned "off") when they are high. The trp operon is regulated by the trp repressor. WebRNA polymerase is the main enzyme involved in transcription. It generally uses single-strand DNA to synthesize complementary RNA strands. In prokaryotes, only a single …
