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...

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...

For regulation of the trp operon, what happens to in the absence of tryptophan? repressor protein (a) It binds to the operator, and represses transcription of genes in the trp operon (b) It cannot bind to the operator, and transcription of genes in the trp operon takes place (c) It binds to the regulatory gene that codes for the TrpR repressor, and represses its transcription (d) It cannot bind to the regulatory gene that codes for the TrpR repressor, and...

here is the diagram
ecause there is no repressor protein attached to the operator, what enzyme con attach to the promoter and move past the operator to transcribe the structural genes? Color this enzyme pink "color the repressor gene purple and the repressor protein it codes for red. Examine the shape of the repressor protein. 45) Is it an active or inactiverepressor protein? The diagram below shows the trp operon when turned off." Repressor gene Promoter Operator Structural genes DNA...

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

When E coli has access to tryptophan in the environment, the trp repressor protein (does or does not) bind to the (operator or activator) and the trp genes (are or are not) transcribed. Select the correct answer in the ( ).

Yet, all the cells in your body contain the same
genes (and same alleles). The difference across cell types
is that genes get selectively expressed (turned on or off)
based on the proteins needed for cellular function given their
environment.

Which of the following features of the trp operon is most essential to the process of attenuation independent of the repressor protein? The order of the structural genes, E, D, C, B, A Allosteric modifications as a result of tryptophan binding. The operator sequence (trpO) The ability of sequences within the leader mRNA to pair with one another and form stem-lopp structures

Page < 2 > of 2 D. The trp operon would be 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...
