Question 24 of 40If a promoter is found within a nucleosome, how would it be possible to express that gene ifneeded?
4/18/20, 9:37 PMAPUS CLE : BIOL133 K006 Fall 19 : Tests & QuizzesPage 9 of 142.5/ 2.5 Points2.5/ 2.5 PointsA. special proteins would open the promoter while located in a nucleosomeB. it would not be possible to express that geneC. slide the nucleosomeD. RNA polymerase would start reading from the downstream side of the promoter Feedback: Feedback: Learning Objective: Describe how access to DNA is controlled by histone modificationQuestion 25 of 40The portions of the mature mRNA where RNA-binding proteins can attach in order to change RNAstability are known asFeedback: Feedback: Learning Objective: Describe the importance of RNA stability in gene regulationQuestion 26 of 40Since phylogenetic trees are essentially ________, they are subject to revision as new information isobtainedFeedback: Feedback: CorrectQuestion 27 of 40
