There are several possible mutations in the trp operon:
trpP -is a mutation in the promoter sequence
that prevents RNA polymerase from binding to the promoter and
initiate transcription of the trp operon genes.
trpOcis a mutation in the operator sequence
that prevents the trp repressor protein from binding to
the operator to block transcription of the trp operon
genes.
trpR-is a mutation in the repressor protein
that either prevents repressor protein from being made or produces
a mutant repressor...

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...

In terms of the Trpoperon, where would the Trp operon repressor protein most likely bind? Drag the "Trprepressor" label to the location where that repressor protein is most likely to bind and exert its effect on the system.

expressed at high levels, comparable to its expression in the absence of trp 6. Based upon what you have learned about the E. coli trp operon, what could you say about expression of its structural genes in cells with large amounts of environmental trp, but expressing a mutant trp repressor that is unable to bind trp? A. The trp operon would be completely repressed due to the abundance of trp B. The trp operon would be transcribed much less than...

Question 11
Question 11 ???????? In the absence of arabinose, the regulatory protein AraC a forms a dimer, binds to two regulatory sequences near the promoter, and activates transcription of the arabinose operon structural genes. b forms a dimer, binds to two distant sites, and forms a DNA loop that blocks access of RNA polymerase to the arabinose operon promoter. c binds to the arabinose operator and represses transcription of the arabinose operon structural genes. d binds to the arabinose...

The trp operon is considered to be repressible because: 1.The repressor binds to the operator, blocking RNA polymerase from transcribing, unless tryptophan is ABSENT 2.The repressor binds to the operator, blocking RNA polymerase from transcribing, unless tryptophan is PRESENT 3.The repressor binds to RNA polymerase at the promoter to help it find the -10 sequence 4.The trp operon has five genes that code for enzymes needed to synthesize tryptophan, only expressed when trp is PRESENT
