Describe the steps of how eukaryotes control gene expression using
transcriptional and post transcriptional .
Explain in details steps clearly and if possible compare it to why
they use this and not OPERONS
27. Be able to describe regulation of gene expression in
prokaryotes (transcriptional, like the Lac Operon)
and in eukaryotes (transcriptional and
epigenetic regulation).
1. Please describe negative control in terms of transcriptional
regulation of gene expression?
2. Please explain the regulation of Trp operon when Trp-tRNA is
available in the cell?
3. What are the classes of Transcription factors based on their
regulatory responsibilities? Please explain if this distinction is
absolute or not?
4. Please explain the mitochondrial protein synthesis by indicating
the mitochondrial protein synthesis apparatus, the mitochondrial
genetic code and so on?
5. Please explain the two hybrid assay?
5. Please...
In combinatorial transcriptional regulation, expression of a
particular gene in a specific cell type is controlled by
Select one:
a. the combination of enhancers present in that cell type.
b. the combination of transcription factors present in that cell
type.
c. the requirement of the gene for the cell’s function.
d. the presence or absence of RNA polymerase in the cell.
In eukaryotic genes, enhancer sequences are usually found
Select one:
a. close to the promoter region of the gene....
Summarized Chapter 17 Gene expression: From Gene to Protein and
Chapter 18 Regulation of Gene Expression. What they were about? Why
they are important? And how they link to other chapters, at least
1/2 page in length for both chapters.
