Describe the different levels at which metabolism can be regulated (transcriptional, translational, post translational).
Describe the different levels at which metabolism can be regulated (transcriptional, translational, post translational).
With diagrams, describe two different mechanisms in which gene expression is controlled at the translational and post-translational levels. You must cite an example for each of these control mechanisms.
Where does the following regulation happen? •transcriptional regulation •post-transcriptional regulation •post-translational regulation •miRNA/siRNA (mRNA degradation) •Ubiquitination/phosphorylation (protein degradation)
1.Describe and compare eukaryotic and prokaryotic flagella. 2.Describe post-translational and cotranslational transport. 3.Describe prokaryotic mRNA translation in detail, including all steps from start to finish, including all factors. 4.Describe the molecular events involved in regulation of the lac operon in response to both glucose and lactose levels, and transcript (mRNA) abundance regulation in the prokaryotic trp operon including attenuation. 5.Completely describe transcript (mRNA) abundance regulation in the prokaryotic trp operon, and discuss whether or not the attenuation mechanism of transcriptional...
8. Control of gene expression in eukaryotic cells occurs at which level(s)? A. only the transcriptional level B. epigenetic and transcriptional levels C. epigenetic, transcriptional, and translational levels
Discuss possible reasons why transcriptional regulation or post-transcriptional regulation may have evolved for different types of genes.
How are post-translational modifications modulated? (I think it's asking how they are regulated? I already know how they are carried out, lipidation, acetylation, methylation, etc.)
One way that tryptophan metabolism in prokaryotes is regulated is “attenuation”. Describe the process of attenuation. Could this process also be found in eukaryotes? Explain.
Draw and describe a theoretical operons including problem, genes regulated, small molecule involved in signaling, which type of transcriptional regulator used, if transcription goes up or down, and how it fixes the problem.
Problem 2 (5 marks) Gene expression can be regulated at 3 levels. Which are these 3 levels? Which mode of regulation is the slowest in response to time, and which is faster? Which is the most efficient in resource use? Explain.
Metabolism can be regulated via Group of answer choices regulating synthesis of particular enzyme. allosteric effectors. feedback inhibition. covalent modification of enzymes. All of the above.
