1.	When DNA segment is in one orientation ____________(a) The gene for FljB and gene encoding FljA are expressed(b) The gene for FliC are expressed(c) The gene for FljB and gene encoding FljA are not expressed(d) The gene for FljB and gene encoding FljC are not expressedThe question was posed to me during an interview.Asked question is from Regulation of Gene Expression in Prokaryotes in chapter Regulation of Gene Expression and Miscellaneous of Biochemistry
Answer» The correct CHOICE is (a) The gene for FljB and gene ENCODING FljA are EXPRESSED Explanation: When DNA SEGMENT is in one orientation, the gene for FljB and gene encoding FljA are expressed; the repressor SHUTS down expression of the gene for FliC.
