Chapter 18 review 1 What are the six mechanisms of gene expression regulation in eukaryotes 2 number histones make one nucleosome 3 Nucleosomes are wrapped into the fiber and further condense on a scaffold into a condensed chromosome during cell division 4 For transcription to occur does the DNA need to be tightly or loosely wrapped to DNA 5 What happens to the nucleosome DNA interaction when histones are acetylated 6 True False Binding to the proximal promoter element activates transcription Why why not 7 TATA binding proteins tell the cell what to transcribe our DNA in and where to transcription 8 How does an enhancer activate expression How does a silencer inhibit expression 9 Are transcription factors always positive regulators of transcription 10 Basal transcription factors are found in what kind of cells 11 What is the name of transcription factors that affect transcription rates 12 Alternative splicing allows one gene to code for mRNA and be translated into many 13 Describe the differences in gene regulation in prokaryotes and eukaryotes
