Tryptophan repressor gene
The operon operates by a negative repressible feedback mechanism. The repressor for the trp operon is produced upstream by the trpR gene, which is constitutively expressed at a low level. Synthesized trpR monomers associate into dimers. When tryptophan is present, these tryptophan repressor dimers bind to tryptophan, causing a change in the repressor conformation, allowing the re… WebThe expression of the tryptophan operon is independent of the availability of tryptophan in culture media. X-chromosome inactivation is known as ______________ The RNAi mediated gene silencing is an ATP-dependent procedure.
