WebThe trp repressor does not always bind to DNA. Instead, it binds and blocks transcription only when tryptophan is present. When tryptophan is around, it attaches to the repressor molecules and changes their shape so they become active. A small molecule like trytophan, which switches a repressor into its active state, is called a corepressor. WebFeb 28, 2005 · Genetic switches can turn genes on and off in different tissues.
