Which of the following mutations would not convert a proto-oncogene into an oncogene? A translocation that places the gene at a new locus where gene expression is increased. A mutation in the coding region that makes the protein resisitant to degradation. Gene duplication. A mutation in the coding region that makes the protein hyperactive. A deletion of an enhancer that lies 3’ to the coding region.
After further investigation, you discovered that HHT1 and HHT2 are produced via alternative splicing. HHT1 is expressed in the liver, and HHT2 is expressed in the pancreas. Regarding the regulation of their expression, you conclude: all answers are possible the regulation occurs at the epigenetic level the regulation occurs at the transcriptional level the regulation occurs at the level of splicing
You have developed an activator of a non-receptor tyrosine kinase. In three different cell types that all contain this receptor your drug has different effects. In cell type A you see activation of gene X and gene Y; in cell type B you note activation of Gene X, but no change in the mRNA levels for Gene Y. In cell type C your drug has no effect on either Gene X or Y. Describe how could each choice (A-D) be a possibility to suit the scenario? a. Genes X & Y are controlled by two separate STATs (STAT X & STAT Y). Cell type A contains both STATs; cell type B contains STAT X only; cell type C has neither STAT. b. Genes X & Y are controlled by two separate STATs (STAT X & STAT Y) and two separate JAKs (JAK X & JAK Y). Cell type A contains both STATs and JAKs; cell type B contains both STATs but JAK X only; cell type C has both STATs but neither JAK. c. Genes X & Y are controlled by two separate STATs (STAT X & STAT Y), two separate JAKs (JAK X & JAK Y) and…
Can you please help with 1a,1b, and 1c please 1a. Find a paper published in a scientific journal between January 2018 and September 2022 that addresses the role of an example of histone modification in affecting expression of a gene by altering histone acetylation/chromatin state of the DNA encoding that gene. What organism and/or cell type did the authors do their study in? 1b. Which histone(s) were affected by the acetylation and/or deacetylation? What gene did they show had altered expression levels in response to the change in histone acetylation? 1c. what effect did the histone modification they studied have on that gene's level of expression - was expression of the gene they examined increased or decreased?
