Question
D Question 3 1 pts Chromatin immunoprecipitation (ChIP) is a powerful technique for identifying the DNA locations associated with a DNA binding protein. ChlP can be utilized for identifying locations in the genome associated with particular histone modifications (such as acetylation or methylation). Which of the following is not true of this application of ChIP? Every histone modification has a well understood function in regulating transcription Antibodies are necessary to recognize the particular modification of interest. Peak regions are typically wider and more diffuse for histone modifications than for transcription factors. Using extensive histone modification data, one can infer histone 'states' that co-associate frequently with particular annotations. D Question 4 Al 1 pts The MD-score approach to inferring transcription factor activity takes advantage of what property of a TF? A transcription factor alters polymerase activity nearby A transcription factor binds to DNA A transcription factor alters chromatin state A transcription factor alters the sequence motifExplanation / Answer
Q3. every histone modification has a well understood functioning intranscriptional regulation is incorrect because many histone modifications are of unknown function.
Q4.;A transcription factor binds to DNA
