Show in the answers are four E. coli partial diploids. They each were assayed for production of the Z and Y genes (B-galactosidase and lactose permease, respectively) in the absence or presence of lactose. Which strain will not show wild-type regulation of lac permease enzyme activity encoded by Y? 0;"poty-11*p*o*zyt oip".*y 11"p*o*zty Opoczty"17"pto*zyt OiSporty lipoto'y O none of the above QUESTION 29 The figure below shows two Topologically Associating Domains (TADs) with one gene in each. During normal limb development in humans, EPHA4 is transcribed, but IHH is not. Transcription of EPHA4 normally is activated by the orange transcription factor. This transcription factor normally only has access to the EPHA4 promoter (and not the IHH promoter) due to the TAD structures shown. A B с IHH OFF EPHA4 ON Deletion of which insulator (A, B, or C; black box) would now allow the orange transcription factor also activate transcription of the IHH gene? oc OA QUESTION 30 In the trp operon, the attenuator adopts different structures depending on whether the leader peptide can be translated completely or not. What would happen if you precisely deleted DNA containing regions 3 and 4 of the attenuatori No transcription will be initiated under any condition Normal regulation of the operon O Any transcripts produced by the Trp operon would be full-length regardless of the concentration of Trp No translation of the Trp biosynthetic proteins even though the complete mRNA is present
