Sigma Alpha Beta O OmegaHow would the removal of the TATA box in a eukaryotic gene impact transcription? Group of answer choices The gene would not be transcribed Transcription would occur more slowly Transcription would occur in the wrong direction Transcription would be less processive The wrong strand would be used as a template for synthesis
- Which basal transcription factor contains a subunit that causes local distortion in DNA so that proteins can assemble to the promoter? TFIIA TFIID TELIH TFUIFWhich of the following is not a control of gene transcription? The repression of a gene by the binding of a transcription factor to a silencer region Methylation of promotor sequences The stabilization of the initiation complex by transcription factors to allow RNA polymerase to begin replication The conversion of heterochromatin to euchromatin through histone demethylation The binding of an inhibitory protein to the 3' UTRWhich of the following are regulatory elements (regions of DNA that are not transcribed or translated, but have a regulatory role)? Insulators Promoters Small interfering RNAS Transcriptional activator proteins Enhancers Transcription factors O Response elements
- How would transcription be affected in eukaryotic cells if Mediator was deleted? Group of answer choices Transcription would occur, but a basal level Transcription would be unaffected with normal levels of transcript produced Transcription would be accelerated Transcription would be aborted and no transcription would take placeA protein binds a DNA sequence several hundred base pairs upstream of a promoter in a eukaryotic organism. This results in an increased rate of transcription of the gene. What type of protein is this? Group of answer choices Activator Silencer Enhancer RepressorWhich of the following functions are characteristic of general transcription factors in eukaryotes? Hint: there may be more than one correct response. Be sure to check all that apply. They inhibit RNA polymerase binding to the promoter and begin transcribing. They bind to other proteins or to the TATA box. They are sufficient to allow high levels of transcription. O They initiate and regulate the transcription of genes. O They bind to sequences just after the start site of transcription.
