question 18

Short Answer

Match the missing words in the following phrase. Tryptophan is an essential amino acid. Wild-type E. coli can synthesize their own tryptophan and are called [A]. Mutants that cannot synthesize an essential nutrient like tryptophan are called [B]. Transcription of the genes for tryptophan synthesis is not [C]: i.e., the genes are transcribed only when needed. Transcription is therefore [D]. When tryptophan is [E], the repressor [F] and transcription of the tryptophan mRNA proceeds. When tryptophan is [G], the repressor [H] and transcription is prevented.
