Part A You were sequencing a region of 200 kb in Effrenium voratum (a member of the family Symbiodiniaceae) and you found two genes, an insulator, and two enhancers, as shown below. Gene A Promoter gene A Enhancer I Enhancer I| Insulator Promoter gene b Gene B Q: What would happen if you do some gene editing and you move the insulator between both enhancers? The newly positioned insulator allows enhancer II to activate gene B transcription The newly positioned insulator allows enhancer I to hyperactivate gene B transcription The new positioning of the insulator prevents gene A expression It will be unaltered The newly positioned insulator prevents enhancer II from stimulating the transcription of gene B
The organization and function of the lac operon in E. coli is shown in the following figures: XXI Transcription Repressor mRNA Translation RNA polymerase M M Flask ZYA XXXX Active M-repressor protein Repressor active, operon off. The repressor protein binds with the operator, preventing transcription from the operon. (a) An inducible operon Copyright © 2007 Pearson Education, Inc., publishing as Benjamin Cummings Allolactose (inducer) Carbon/Energy Source 0 Z MInactive repressor protein (a) An inducible operon Transcription Translation XXX Permease B-Galactosidase Transacetylase Operon mRNA 3 Repressor inactive, operon on. When the inducer allolactose binds to the repressor protein, the inactivated repressor can no longer block transcription. The structural genes are transcribed, ultimately resulting in the production of the enzymes needed for lactose catabolism.

Why are bacterial polyribosomes formed co-transcriptionally? Check all that apply. Bacterial ribosomal subunits cannot enter the nucleus. Bacterial ribosomal subunits can enter the nucleus. Bacterial ribosomal subunits cannot enter the nucleoid. Bacterial ribosomal subunits can enter the nucleoid. Bacterial ribosomal subunits cannot bind mRNAs before transcription termination. Bacterial ribosomal subunits can bind mRNAs before transcription termination.
