Question

Question 1 Match the term with the best definition or description; most topics relate to the regulation of gene expression. General type of protein which will increase transcription rates when it attaches to a site A. Factor connected to a particular gene - B. Co-repressor C. Enhancer D. Promoter E. Structural F. Intron G. Activator H. Operator I. Basal transcription J. Glucocorticoid receptor K. Sigma factor L. Mediator M. Inducer N. TATA box O. Repressor The rates of mRNA produced when only the general transcription factors bind (eukaryotic cells) - # A small effector molecule that triggers a protein to bind to the DNA which reduces or stops transcription The general term for a sequence of DNA to which a protein attaches, often to regulate transcription - . # The specific name for a sequence of DNA where a regulatory protein attaches, which results in increased transcription rates (in a eukaryotic cell) *The general name for a protein that attaches to DNA to play some role | - A small regulatory molecule that attaches to a regulatory protein and it may cause the protein to unbind from the DNA, which allows transcription to occur. A protein complex that serves as a bridge between proteins at the promoter and regulatory proteins bound to the DNA # In a prokaryotic cell, a DNA sequence where the protein that stops transcription binds - In a prokaryotic cell, a group of genes that are regulated and transcribed together as a . # A sequence of DNA that is always at the start of any gene; it is where RNA polymerase, - # A protein which, when it binds to the DNA at regulatory sites, it has the effect of . # A type of protein in eukaryotes which binds to the DNA, at a site that is always just single mRNA and often other proteins, bind to the DNA to begin transcription reducing or stopping transcription of regulated genes. Shine-Dalgarno sequence Q. Operon R. General transcription factor S. Element upstream from the transcription start site, and is required to enable RNA polymerase to begin transcription. . # A type of protein that is used in prokaryotic cells which works with RNA polymerase to find the right location at the start of a gene in order to attach and begin transcription. The name for any gene that produces mRNA when transcribed, and thus encodes protein sequences # A sequence that, because of the type of nucleotides found in it, creates a "weak spot" - for the double strands to be separated to allow RNA polymerase to read the template strand.
