Acetylation of CpG islands leads to repression of transcription. d. CpG islands code for RNA molecules that activate transcription.
Which of these is NOT true of nucleosomes? A. Some post-translational modifications to histone proteins serve as binding sites for transcription factors. B. The position of nucleosomes is fixed on the genome and can not be changed. C. The position and post-translational modifications of histones can be inherited through mitosis. D. The binding between DNA and histone proteins can be disrupted by post-translational modifications.
How does adding a methyl or acetyl group to a histone protein alter gene activity?A. A methyl group turns genes off. An acetyl group loosens histone’s grip and increases gene activation.B. A methyl group turns genes on. An acetyl group tightens histone’s grip and decreases gene activation.C. A methyl group increases the probability of a mutation, whereas an acetyl group decreases the probability.D. A methyl group decreases the probability of a mutation, whereas an acetyl group increases the probability.
Transcriptional activation of eukaryotic genes involves which of the following events? a. Changes in nucleosome locations b. Changes in histone composition within nucleosomes c. Changes in histone modifications d. All of the above
A procedure called chromatin immunoprecipitation allows scientists to determine where aparticular protein is located in the genome. You conduct this procedure for a human regulatorytranscription factor and a histone acetyltransferase, and you find that the two proteins arepresent together at the promoters of many genes. Is the transcription factor more likely to bean activator or a repressor? Why?
1)A. how do you read a sequence of DNA (template or non-template strand) to convert it an mRNA sequence and to a protein? B.How does chromatin remodeling regulate gene transcription? C. What are the major differences between gene expression in bacteria and eukaryotes D. How are non-coding regions involved in gene transcription? E. Explain how eukaryotic genes sometimes produce multiple protein products?
Why are errors in DNA methylation so destructive to cells? a. They cause improper activation or inactivation of DNA segments coding for important genes or micro RNAs. b. They cause improper methylation of proteins. c. They cause improper methylation of mRNA transcripts. d. All of these are possible explanations for methylation error damage..
During X inactivation, all but one gene get silenced on one X chromosome. Why does one gene escape the inactivation? A) That is the gene responsible for inactivating the others B) Two copies of that gene are needed in females, so both are active C) X inactivation is rarely complete, so occasionally one or two genes get activated by mistake D) That is the gene that encodes the methyltransferase needed to methylate the genome.
