Regulation of gene expression in eukaryotes can occur:
Step by step
Solved in 2 steps
- The diagram below shows the structure of DNA from the level of a gene to a condensed mitotic chromosome. At each of the four locations marked, indicate how a gene may be regulated by selecting from the choices given. Some answer choices may fit into more than one position; however, you should use each answer choice only once. Choices given: Alternative splicing within the gene sequence can lead to different forms of mRNA. A promoter region can be blocked by another protein. Histone deacetylation can prevent DNA from unwinding. A regulatory region can be bound and increase transcription rates.Determine whether the following will increase or decrease gene expression: mRNA degradation mRNA capping Binding of a transcriptional activator Ubiquitination of a protein and targeting to the proteasomeDiscuss how the expression of a protein can be regulated post transcription in eukaryotic cells through, using the following key terms: Degradation of mRNA (two ways) Blocking translation Degradation of the protein
- The 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.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.Which 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.
- Transcription factors function in the nucleus. However, like (almost) all eukaryotic proteins,they are translated in the cytosol. Can you draw a visual to explain how transcription factor proteinsenter the nucleus from the cytoplasm? Can you also include a representation of relevant proteins and proteindomains to explain how these proteins reach their destination. Thank youBelow 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.Given the following schematic for a gene and its associated regulatory regions, answer the following questions by placing the correct letter in the provided blanks please put in the correct letter for the questions What region would provide cell type-specific expression of genes? region What site would significantly increase gene expression rates? = region What region or regions of this gene’s coding sequence are expressed as amino acids = region
