X-chromosome inactivation (as in the case of the female tortoiseshell cat) histone dephosphorylation histone methylation histone deacetylation E. histone phosphorylationList the following steps of gene expression in eukaryotes in chronological order. Also indicate which events take place in the nucleus and which take place in the cytoplasm. RNA processing, transcription, translation, RNA breakdown into nucleotidesGenetic expression in general can be regulated at various stages. Identify specific processes that control gene expression at the: a. transcription level - b. post-transcription level - c. translation level -
- Regulation of Gene Expression by Chromatin Modification is Local and Dynamic! What does the statement above mean?Describe the role of transcription elements in regulation of gene expression in eukaryotic cells.Identify which eukaryotic level of gene regulation is most applicable in the given examples. (Pre-transcriptional control, Transcriptional control, Translational control, Post-translational control) The glycolytic enzyme pyruvate kinase is activated by dephosphorylation and inactivated by phosphorylation. In the fruit fly, genes for rRNA can be replicated more or less often compared to the rest of the chromatin depending on the needs of the cell. In the human beta-globin, two introns are spliced out in order to produce the mature mRNA. DNA methylation can change the degree of condensation of the chromatin.
