The RNA polymerase holoenzyme ?2?? \'? carries out transcription inprokaryotes. a) Which two of the following are functions of the RNApolymerase ? subunit? b) How would transcription be affected if the? subunit were part of the ?2?? \' core? c) Which would you expectto have more types of ? factors � a free-living prokaryote in afluctuating environment or a prokaryote in a relatively stableenvironment with adequate nutrients?
The RNA polymerase noioenzyme alpha carries out transcription in prokaryotes. Which two of the following are functions of the RNA polymerase sigmma subunit? to decrease the affinity of RNA polymerase for most DNA to increase the rate of translation to terminate transcription to form part of the core RNA polymerase enzyme to recognize the promoter DNA sequence How would transcription be affected if the a subunit were part of the core? Transcription would be slower. Transcription would be faster. Transcription speed would not change much. Which would you expect to have more types of sigmma factors - a free-living prokaryote in a fluctuating environment or a prokaryote in a relatively stable environment with adequate nutrients the organism in the stable environment, because nutrients are consistently available for growth and reproduction the organism in the stable environment, because increased transcription is needed to metabolize nutrients the organism in the fluctuating environment, because general transcription is faster with more sigmma subunits the organism in the fluctuating environment, because it is exposed to more extremes
