B) 7000-nucleotide trp mRNA
C) 130-nucleotide trp mRNA

When tryptophan levels are low, the cell needs to produce more tryptophan. This is facilitated by the transcription of the trp operon, which includes a 162-nucleotide leader sequence and the full-length 7000-nucleotide trp mRNA that encodes enzymes necessary for tryptophan synthesis.
