Provide two examples of cis-acting regulatory elements.
In the GAL gene system, __________ are cis-acting regulatory elements, and __________ protein is a trans-acting regulatory protein.
1. Gene regulatory elements are a) trans-acting transcription factors b) cis-acting transcription factors c) trans-acting DNA sequences d) cis-acting DNA sequences 2. The unwinding of DNA during the initiation of transcription is mediated by the helicase activity by: a) TFIID b) TFIIH c) TFIIF d) TFIIE
How do enhancers differ from promoters as cis-acting regulatory sequences in eukaryotes?
Choose the cis-elements. Click on the cis regulatory elements only. Control of eukaryotic gene expression (gene control) can occur at multiple levels from DNA accessibility to post-translational changes to polypeptides/proteins. Silencers, repressors, transcription factors, activators, enhancers, insulators histone acetyltransferases (HATS), histone deacetylases (HDACs) histone remodellers and DNA methyltransferases all play a role in gene control.
28. Regulatory transcription factors (the proteins themselves) A. are trans-acting factors. B. are cis-acting elements. C. are promoters. D. are the same in all cells regardless of tissue type. E. are encoded by centromeres. 29. The process that leads to development haploid gamete is best described as ________. A. segregation B. independent assortment C. mendelian inheritance D. dominance 30. A cross between two individuals with different phenotypes that resulted in approximately 50% of each type of offspring would indicate the...
Define cis-acting elements and trans-acting factors. How do they in a eukaryotic cell?
What are “cis-regulatory elements,” “trans-regulatory factors,” “exons,” “introns,” “untranslated regions,” “proximal promoters,” “enhancers,” “repressors,” "activators,” “caps,” and “poly-A tails”? Which are protein coding sequence (or are actual proteins); which are not? Which make it into mature mRNA?

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...
