Study Questions Describe the roles of cis-acting sequences and trans-acting factors in the control of eukaryotic gene expression. What transcription factors are required for the successful transcription of eukaryotic DNA by RNA polymerase II? Describe the relationship between the promoter, CCAAT box, GC box, enhancers and silencers. What specific role might methylation play in the control of eukaryotic gene expression? How was it determined that trans-acting factors have two functional domains? Describe several classes of eukaryotic trans-acting factors. Discuss the relationship between the ligand and receptor protein during the activation of gene expression via phophorylation. Copyright © 1997. Phillip McClean
