Concept explainers
The interphase nucleus appears to be a highly structured organelle with chromosome territories, interchromosomal compartments, and transcription factories. In cultured human cells, researchers have identified approximately 8000 transcription factories per cell, each containing an average of eight tightly associated RNA polymerase II molecules actively transcribing RNA. If each RNA polymerase II molecule is transcribing a different gene, how might such a transcription factory appear? Provide a simple diagram that shows eight different genes being transcribed in a transcription factory and include the promoters, structural genes, and nascent transcripts in your presentation.

- What effect would inhibitors of histone deacetylases have upon transcription? Group of answer choices They would increase transcription by making the chromatin more compact They would increase transcription by making the chromatin less compact They would decrease transcription by making the chromatin more compact They would decrease transcription by making the chromatin less compact For this question, we will consider a eukaryotic mRNA that has four exons (E1, E2, E3, E4) and three introns (I1, I2, I3). What could occur if a protein were to bind over the 3' splice site of intron 2 (I2)? Group of answer choices The processed mRNA would consist of: E1+E2+E3+E4 The processed mRNA would consist only of: E1+E3 The processed mRNA would consist only of: E3+E4 The processed mRNA would consist of: E1+E2+E4arrow_forwardRefer to figure, which shows the distribution of histone H2A.Z on nucleosomes near a transcription start site. What experimental technique would have been used to generate the data for this figure? Briefly describe the operation of this technique.arrow_forwardYou 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 expressionarrow_forward
- The following DNA nucleotides are found near the end of a bacterial transcription unit. 3′–AGCATACAGCAGACCGTTGGTCTGAAAAAAGCATACA–5′ Q. Is this terminator rho independent or rho dependent?arrow_forwardHow do I draw the sequence and explain the process for each step? Draw the sequence of molecular events that occurs to induce STAT transcription factor localization to the nucleus. To complete this, you will draw the first step that occurs, then draw a new figure with the second step that occurs, then draw a new figure with the third step that occurs, and so on until you have completed all of the steps. On the drawing, briefly label each molecular event (each drawing). For this brief label, explain what is happening during each step.arrow_forwardShown below is a schematic drawing of a gene, with the transcription unit divided into numbered regions. The arrows (;) indicate transcription initiation sites, "D" indicates a splice donor site, "A" indicates a splice acceptor site, and "An" indicates a polyadenylation signal. Give all the possible fully processed mRNAs that could be produced from transcripts of this gene (you don't need to draw anything, just list the regions that would be included in each mRNA by number).arrow_forward
- What is the complementarity rule that governs the synthesis of an RNA molecule during transcription? An RNA transcript has the following sequence: 5′–GGCAUGCAUUACGGCAUCACACUAGGGAUC–3′ What is the sequence of the template and coding strands of the DNA that encodes this RNA? On which side (5′ or 3′) of the template strand is the promoter located?arrow_forwardWhat is meant by the term chromatin remodeling? Describe the importance of this process to transcription.arrow_forwardIn 3-4 sentences eachExplain the difference between prokaryotic and eukaryotic transcription. Explain the difference between an activator and a repressor? Explain the difference between a promoter and an enhancer? Explain the difference between an intron and an exon? Explain what happens when eIF-2 is phosphorylated and when it is not phosphorylated?arrow_forward

TFIIDarrow_forwardin the human gene for the beta chain of hemoglobin, the first 30 nucleotides in the amino acid coding region is represented by the sequence 3'TACCACGTGGACTGAGGACTCCTCTTCAGA-5'. What is the sequence of the partner strand? If the DNA duplex for the beta chain of hemoglobin above were transcribed from left to right, deduce the base sequence of the RNA in this coding region.arrow_forwardWhat are the functions of transcriptional activator proteins and repressor proteins? Explain how they work at the molecular level.arrow_forward
