How does the Trp repressor prevents RNA polymerase from initiating transcription? by blocking the ribosome binding site by forming a loop in the operator that restricts the passage of the polymerase by binding to the polymerase to inhibit its catalytic activity by physically blocking the DNA binding site of RNA polymerase

Which of the following correctly describes eukaryotic transcriptional control? a. A transcription factor is a DNA molecule that helps RNA polymerase to bind to the enhancer of a specific gene. b. An enhancer is a protein that encourages gene expression by binding to the DNA. c. The promoter is the region of RNA where DNA polymerase will bind to begin transcription. d. The interaction of multiple transcription factors may be required in order to transcribe a...

on Select all characteristics of proteins that are positive regulators of transcription Check All That Apply Positive regulators of transcription never need to associate with any other molecule to bind DNA. O Positive regulators help recruit ribosomes. O Positive regulatory proteins can affect only one operon. O Positive regulators often bind effectors before binding with DNA. O Activators regulate some degradative pathways. O Positive regulators help recruit RNA polymerase. Prey e to search

Transcription is terminated, when a characteristic RNA structure _____ is formed by local RNA palindromic sequences at the 3’- end. The structure interacts with RNAP-bound NusA, causing dissociation of RNAP from template DNA. The RNAP dissociation is stimulated by sequence-specific binding of _____ proteins to the transcribed RNA, enhancing termination of transcription. Select one: a. hairpin ;;;; rho b. hairpin ;;;; sigma c. beta-turn ;;;; rho d. beta-turn ;;;; sigma e. None of these
