A mutation in the operator of the trp operon prevents the repressor to bind to the operator, even in the presence of tryptophan. What is true with respect to the bacteria carrying this mutation? Select one: a. The bacteria will transcribe the genes of the trp operon even when tryptophan is present in the environment b. Tryptophan would not be able to bind to the repressor protein c. Small amounts of tryptophan will be lethal for the bacteria d. The...

Which of the following amino acid changes could result from a mutation that changed a single base? For each change that could result from the alteration of a single base, determine which position of the codon (first, second, or third nucleotide) in the mRNA must be altered for the change to result. a) Trp → Stop b) Ser → Phe c) Asp → Tyr d) Ile → Thr
