Students have asked these similar questions
Compare the control of gene regulation in eukaryotes and prokaryotes at the level of initiation of transcription. How do the regulatory mechanisms work? What are the similarities and differences in these two types of organisms in terms of the specific components of the regulatory mechanisms? Address how the differences or similarities relate to the biological context of the control of gene expression.
Provide a detailed description of gene expression and control in prokaryotes. Provide a detailed description of proteins critical for this process. (please hand draw a figure showing gene expression and control in prokaryotes and the proteins involved)
Create a Venn diagram to compare and contrast the process of gene expression in Bacteria versus eukaryotes. Remember that “gene expression” can include any part of transcription or translation. Try to be as thorough as you can about what aspects of this process are similar between the two taxa, and what characteristics are distinct to only Bacteria or eukaryotes. Plase include a minimum of 15 items in the Venn diagram.

Which of these three mechanisms will be most effective in each of the following situations? A. Shutting down the synthesis of a polypeptide B. Shutting down the synthesis of mRNA C.

One mechanism by which antisense RNAs act as negative regulators of gene expression is by base pairingwith the ribosome binding site on the sense mRNA toblock translation. In a second, alternative mechanism,the act of transcribing an antisense RNA can somehow prevent RNA polymerase from recognizing thesense promoter for the same gene. Design an experimental approach that would enable you to distinguishbetween these two modes of action at a specific gene.(Hint: What would be the outcome in each case ifhigh levels of the antisense RNA were transcribedfrom a gene on a plasmid?)arrow_forward
