- Which of the following is NOT a reason cells regulate gene expression at a level other than the transcriptional level? Some proteins are only required in part of the cell and transcriptional control will only regulate the mRNA/protein throughout the cell. The core promoter for many genes is the same, so these genes will always be transcribed in the same cells. Differential gene expression in different cell types requires regulation of gene expression at levels other than transcription. Transcription and translation are realtively slow processes, so cells need to regulate gene expression post-transcriptionally if they require a fast change in expression of a gene. Not all cells are transcriptionally active (meaning they do not transcribe any genes), so these cells need to regulate gene expression post-transcriptionally.In the regulatory switch experiment, which level of gene expression regulation is the focus? Regulatory switch Enhancer Mouse Enhancer Bat Enhancer Bat-mouse translation level regulation transcription level regulation post-translational regulation O post-transcriptional regulation (RNA modification)What level of control of gene expression is defined as regulating whether a particular mRNA is actually used in proteins synthesis and if so for how long a period of time transcriptional leve control translational leve control processing level control replication level control denaturation level control
- What is the role of general transcription factors? GTFs bind to enhancers or silencers and regulate transcription GTFs bind to the core promoter and allow transcriptional initiation GTFs are cis-acting regulatory sequences GTFs regulate the length of the mRNA GTFs are part of the RNA polymerase II holoenzyme, and control transcription initiationThe most common type of regulation of gene expression occurs at the level of transcription. Name other types of gene regulation for gene expression in eukaryotic cells. Name types of gene regulation unique to eukaryotic cells versus prokaryotic cells.At which stage of the Central Dogma does MOST of the regulation of gene expression occur? O Post-transcriptional processing of the pre-MRNA O Post-translational processing of the polypeptide chain Transcription of pre-mRN O Translation of protein
- Which of the following describes transcription factors? The addition or deletion of methyl and acetyl groups to regulate transcription Proteins that specifically bind to promoter or enhancer regions to initiate transcription The transcription initiation sites of DNA that bind RNA polymerase DNA regulatory elements that actively repress the transcription of a gene O Varying sequences that are or are not included in the instructions to make a proteinBelow is a model of a signal transduction pathway that results in the transcribing of mRNA: Receptor protein Transcription factor Phosphorylation cascade DNA mRNA What is the best description of what would happen if the phosphorylation cascade resulted in a phosphate being attached to the transcription factor? O mRN would not stop being transcribed from the DNA. O The phosphorylation cascade would continue to release excess phosphates. O mRNA would stop being translated from the DNA. O Receptor proteins would not bind to the signaling hormone.Which of the following correctly shows different regulatory mechanisms ranked from fastest to slowest? Answers A -E A.
