Gene Expression refers to the presence of functional gene product in the cell. Pick out the odd one that could NOT alter the levels of this functional gene product post-translation? Poly-A tail of mRNA ubiquitination followed by proteasomal degradation chemical modification of the protein e.g: phosphorylation or dephosphorylation Lack of chaperones that properly fold the proteins QUESTION 18 The binding of iron regulatory protein (IRP) to the iron response element (IRE) in the 5'UTR of the ferritin mRNA causes increases Ferritin (protein) synthesis in the cell decreases Ferritin (protein) synthesis in the cell has no effect on Ferritin (protein) levels in the cell QUESTION 19 What is Not true about transcriptional Silencer and Enhancer elements? are orientation independent can be upstream or downstream of the promoter region can be present in an intron sequence of the gene directly bind RNA polymerase
