Which of the following is NOT a purpose of the promoter?

A encode for proteins

B orient the RNA polymerase to begin transcription of operons or genes

C allow for differential expression of genes

D all of the above

Expert Solution

option d

Eukaryotic promoter regulatory sequences typically bind proteins. In genetics, a promoter is a region of DNA that initiates transcription of a particular gene.

Promoters are DNA sequences whose purpose is not to encode information about the organism itself, but rather they serve as a kind of "On" switch to initiate the biological process of transcription for the genes which follow the promoter DNA sequence

Explain Operons Detailly a. Describe the purpose of the essential operon components (promoter, operator, genes, regulatory protein). Keep your answers general for all operons. b.Contrast repressible and inducible operons. Include descriptions of differences at the level of both function and molecular interaction. c. Metabolically why does it make sense that the Trp Operon is a repressible operon and the Lac Operon is an inducible operon?

Your band hires a promoter to promote its shows. A good promoter will result in a sold-out show 90% of the time. A promoter who isn’t good will result in a sold-out show 55% of the time. You initially figure that there is a 70% chance that this promoter is good. Your first show sells out, then the next shows fails to sell out. What is the new probability that the promoter is good? Round your answer to the nearest...
