You are studying how gene expression is regulated in the cell. For gene z, you find that while there are high levels of mRNA in the cell, there are low levels of the protein encoded by gene z. Describe a regulatory mechanism that could explain this finding that occurs after translation.
a. How do bacteria increase the efficiency of gene expression? Is this possible in eukaryotes? b. A mutation in the promoter of Gene K disrupts an enzyme binding site and results in the loss of Gene K expression. Is this change in gene expression likely happening at the transcriptional or the translational level? Explain. c. Propose three different mutations to prevent initiation, elongation, and termination of bacterial transcription, respectively. Explain how/why each mutation would prevent its respective step. (Hint: mutations can be in genes that encode proteins or regulatory DNA sequences)
The figure below depicts the mechanism of iron homeostasis in mammalian cells, in which ferritin is produced to sequester excess iron in high iron conditions, and transferrin receptor is produced to import iron in low iron concentrations. (a) Ferritin mRNA 5% IRE i 5% Inactive IRE-BP Active IRE-BP High iron Coding region - An 85 H₂N COOH Translated ferritin Low iron Coding region A No translation initiation (b) TfR mRNA High iron 5'- Coding region Inactive IRE-BP Active IRE-BP Low iron 5'- Coding region IRES An N a) A mutation in a mammalian cell line in tissue culture was found that constitutively expresses Ferritin. Suggest a possible mutation that could account for this. Degraded mono- nucleotides degradation -Mutation in ires binding protein where it does not bind to iron suggests that cell lysate has high transferrin and low ferritin. I b) Upon further examination of the cell line, it was found that there was normal expression of the Transferrin Receptor. Would the mutation you…
MRNAs and eukaryotic cells receive different modifications than those in prokaryotic cells, because eukaryotic mRNAs must be able to accomplish different things. Which of the following describes events that are necessary for an mRNA to be expressed in a eukaryotic cell, but are not necessary for mRNAs in a prokaryotic cell? select all that apply A) introns must be removed from the eukaryotic mRNA B) The mRNA must leave from the nucleus C) transcription factors must bind to the mRNA in a eukaryotic cell after it is transcribed D) A ribsome must bind to the mRNA .
The siRNA and miRNA pathways share many similarities and also have some differences. Which of the following is true about these two noncoding RNA classes in regulating gene expression? O Both of them utilize the internally generated RNAS as sources to produce the short regulatory RNAS O Both of them need Dicer to process the long RNAS into short double-strnaded RNAS Both of them required perfect match between the short noncoding RNAS to the MRNAS Both of them end up with complete degradation of the target mRNAs

Below 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.
