What types of mutations would prevent ρ-dependent termination? C. If a mutation prevented transcriptional termination at the end of a gene, where would gene transcription end? Or would it end?
You are teaching a class on the regulation of eukaryotic gene expression. In order to demonstrate this complex process, you decide to draw for the class a typical eukaryotic gene/transcription unit with its major regions, such as the promoter regions, where the RNA polymerase II and transcription factors would bind From the list given - choose all components that you think are part of a typical eukaryotic gene From the list given - choose all the regulatory sequences that you think would control the expression of this eukaryotic gene From the list given - choose all of the regulatory proteins that would bind the eukaryotic gene to control its expression
In order to manufacture insulin for patients with diabetes, scientists create recombinant DNA by inserting a human insulin gene into bacterial DNA and have the bacteria produce human insulin. Based on what you have learned in this unit about gene expression, what must the scientists do to the DNA sequence of the human insulin gene BEFORE inserting it into the bacteria, in order to have them produce the same insulin sequence that humans would produce? Explain.
Which of the following gene expression regulatory mechanisms saves the most energy but takes the longest to fully express the genes once signaled? a. transcriptional regulation b. post-transcriptional regulation c. post-translational regulation d. translational regulation
Name the lambda promoters whose expression is regulated by the cro protein. For each promoter you named, is cro an activator or a repressor of transcription from that promoter?
Transcriptional repressor proteins (e.g., lac repressor), antisense RNA, and feedback inhibition are three different mechanisms that turn off the expression of genes and gene products. Which of these three mechanisms will be most effective in each of the following situations? A. Shutting down the synthesis of a polypeptide B. Shutting down the synthesis of mRNA C. Shutting off the function of a protein For your answers to parts A–C that list more than one mechanism, which mechanism will be the fastest or the most efficient?
Why is regulating transcription the main way that cells control gene expression? A. Because transcription is the last step in gene expression, stopping here ensures that the cell has a stockpile of proteins to prepare them from all unexpected environmental changes. B. Because transcription involves interactions with DNA, preventing transcription reduces the changes of mutation in the cell’s genome. C. Because transcription is the first step in gene expression, stopping at transcription reduces the amount of energy and resources used by producing unnecessary gene products. D. Because transcription is the shortest step in gene expression, preventing transcription has little effect on the rate of protein production.
You observe that a particular gene is being transcribed during development. How can you tell whether the expression of this gene is under transcriptional or translational control?
