Do each of the following terms apply to a regulatory protein, a segment of DNA, or a small effector molecule? A. Repressor B. Inducer C. Operator site D. Corepressor E. Activator F. Attenuator G.

Why must chromatin be remodeled at a eukaryotic promoter? Histone proteins must be added to the promoter so they can recruit RNA polymerase II Histone proteins are blocking promoter sequences recognized by general transcription factors (GTFs) Space needs to be made for the ribosome to bind to a nascent (i.e. newly transcribed) mRNA Because enhancer regions need to be exposed for general transcription factor binding To allow the spliceosome to remove exons from the mRNA during transcription
A mutation in the trp repressor gene that prevents the apo-repressor from binding the co-repressor What is the correct option from the choices below? causes the Trp repressor to permanently bind the trp operator. leads to a high level of transcription initiation from the trp promoter, even when tryptophan is present in the medium. does not lead to a high concentration of mRNA molecules that code for the structural genes trp E, D, C, B, A, when tryptophan is present in the medium, because attenuation of the operon will still work. a and b, but not c b and c, but not a

Mutations in bacterial promoters may increase or decrease the rate of gene transcription. Promoter mutations that increase the transcription rate are termed up-promoter mutations, and those that decrease the transcription rate are termed down-promoter mutations. If the promoter for the lac operon is TATGTT, would the following be uppromoters or downpromoters?A. TATGTT to TATATTB. TATGTT to TTTGTTC. TATGTT to TATGAT

Result in an increase or decrease in the amount of mRNA transcribed
The MAT locus allows yeast to switch mating type through a very complex mechanism. However, it has informed us a great deal about what aspects of gene expression typical to all organisms?
