2. Please describe how TPP riboswitch aptamer regulates gene expression.
TPP Thaim pyrophosphate in bacteria commanly repressed gene expression by terminating transcription by blocking ribosome binding.or regulate gene expression by modulate RNA SPLiCING in EUCARIYOTS .
Riboswtches are metabolite binding elements that useuly located in non coding region of mRNA .
Bacterial TPP riboswtches regulates gene expression almost exclusively control of transportation alongatio and translation initiation these are more drivers and intrcated .
A DIAGRAM OF TPP RIBOSWTCHES REGULATION
2. Please describe how TPP riboswitch aptamer regulates gene expression.
Describe in as detailed a way as possible how a chromatin remodeling complex regulates gene expression. Please describe how all of the following factors work together… The chromatin remodeling complex, The nucleosomes, The transcription factors, The TF binding site, The TATA box, The RNA polymerase
25. What is a riboswitch? A. a small molecule that regulates the translation of specific mRNAs B. a gene regulatory protein that turns on the expression of ribosomal proteins C. an mRNA that can regulate its own transcription and translation D. a ribosome that participates in attenuation E. when the antisense RNA binds to the transcript 26. In the Ames Test, the appearance of his+ revertants in the presence of a non-mutagenic control compound indicates that _______. A. liver extract...
What is DNA methylation? Describe how this mechanism regulates the expression of genes. What can happen when the DNA is hyper-methylated? Pick and describe a disease that results from DNA hyper-methylation.
1. One way that gene expression is regulated is in the remodeling of chromatin. Describe the three mechanisms of changes in the structure of the nucleosome as well as the effect of acetylation and methylation on gene expression? 2. Describe the impact of deletion, duplication, inversion and translocation on chromosome structure and gene expression of those chromosomes? 3. Explain how ATP is produced in respiration? Please help with this picture below as well! It’s a gram positive and negative bacteria.
Understanding control of gene expression by chromatin regulation We discussed how maternal grooming behavior regulates anxiety and stress response in rats. Rats raised by low-care mothers grow up to be more anxious and guarded adults. Rats raised by high-care mothers on the other hand become more relaxed adults. Below are two key results from the study that discovered this phenomenon. Scientists looked at DNA methylation in the promoter of a gene called glucocorticoid receptor which is expressed in the hippocampus...
15. Describe the gene expression at the lac operon in the following conditions. Please discuss all components involved and how they regulate the expression: a. Absence of glucose; presence of lactose b. Absence of lactose; presence of glucose

Describe how the expression of this gene is regulated. Include the roles of all key players (GAL3, GAL4, GAL80, Gene promoter, RNA polymerase, and transcription factors) illustrated. Understanding regulation of transcription in eukaryotes. The images below depict how the expression of a gene required to break down lactose in yeast is regulated. The top image illustrates the key regulators of the process. The bottom two panels illustrate what happens in the presence and absence of galactose. Describe how the expression...
1) Explain how eukaryotic gene expression is controlled from a distance 2) Describe the experiments that showed all differentiated cells contain all the genetic instructions to direct the formation of a complete organism. 3) Explain the structure of tryphtophan operon and how this operon is regulated at the low and high concentration of tryphtophan.
Generally, describe how the sequencing data was analyzed for differential gene expression. How was it determined that genes were differentially expressed using DESeq? 2. 3. At the end of the DESeq pipeline, you got a list of 1000 differentially expressed genes. Which command would have changed the number of differentially expressed genes? How would it have done so?
