Gene Regulation Welcome to your Gene regulation question series Prokaryotic and eukaryotic organism share regulatory genes sequences. True Flase None Which of the following genes are not required to be governed by the operon Genes of glycolytic pathway Genes of larger protein complex Genes with co-ordinated function Genes essential under specific condition None Helix-turn-helix Zinc finger Homeodomain Leucine zipper None In zinc finger motif zinc elements interacts with Hydrophobic interaction Coordinate bond Cross linking Hydrogen bon None Find the correct sequence of transcription attenuation of the trp operon A. Pairing of sequence 3 and 4B. Formation of stem-and loop structureC. Structural contraints in translationD. Transcription termination ABCD DCAB CBAD ABDC None Promoter of a gene is required for Transcription termination Transcription initiation Binding of DNA polymerase to the DNA Splicing site None In zinc finger motif, Zn2+ ion directly interacts with DNA True False None What is true about isopropylthiogalactoside (IPTG) A lac operon inducer A substrate for β-galactosidase A repressor None of the above None In which of the following condition the transcription of trp operon will be stopped, When charged tryptophan tRNA (Trp-tRNATrp) concentration is high and sequence 3 base pairs with sequence 2 When charged tryptophan tRNA (Trp-tRNATrp) concentration is high and sequence 2 is unavailable for pairing When sequence 4 is unavailable as a result of pairing between sequence 2 and 3 When there is no requirement of protein synthesis None Which of the following phenomenon may occur when repressor molecule binds to signalling molecule? Increase in the rate of transcription Decrease in the rate of transcription Halting transcription Transcription process stays unaffected I and II None Promoter binding specificity of RNA polymerase can be modulated True False None Where is the attenuator sequence is located in trp operon, 3’end of trp operon mRNA In the leader region 500 bp downstream promoter Ribosomal binding site of last gene None Time's up
