1. trans-acting factors are able to regulate target genes from any chromosome, whereas cis-acting elements can only regulate genes located in the same chromosome. a. True only in operons. In Eukaryotic systems, trans-acting factors only regulate genes in the same chromosome. b. True only in Eukaryotes. Prokaryotes don’t have cis-acting elements. c. True for any organism. d. False. The statement is erroneous 2. Unlike activators, repressors never affect chromatin structure. Repressors inhibit transcription only by binding to the binding sites...

1.) Which antibiotic target could have the most toxicity associated with it? A. 50 S ribosomal subunit B. folic acid synthesis metabolic pathway C. cell wall D. cell membrane 2.) You are hoping to discover a new antimicrobial drug that targets fungi. Which structure might you hope to have your antimicrobial target to minimize toxicity? A. ribosomes B. chitin C. peptidoglycan D. phospholipids of plasma membrane 3.) An antiviral drug that blocks the activity of the enzyme integrase is used...
