What is true of CHIP-Seq experiments? they require treatment with DNase they require a "reference" genome sequence to be available they should provide a complete genome sequence when done properly they depend on in vitro translation they are useful for assaying histones but not other DNA-binding factors

ChIP-seq is widely used to analyze the distribution of specific proteins throughout the genome. Which is NOT a requirement for doing ChIP-seq? Group of answer choices: Next Generation Sequencing (i.e., Illumina sequencing) is required to analyze the sequence composition of the DNA recovered from the immunoprecipitate. The sequence of the genome for the organism you are studying must be known. An antibody must be available to immunoprecipitate the protein of interest. The protein of interest must crosslink either directly or indirectly to the DNA. Intact messenger RNA must be purified from the cells.

The Encyclopedia of DNA Elements (ENCODE) project aims to discover functional elements in DNA. One technique employed is DNase-seq. This technique employs a DNase enzyme that digests accessible regions of chromatin, while inaccessible regions remain undigested. The undigested DNA is then sequenced. Which of the following is likely true of the DNase-seq results? Choose one or more: A. Centromeric DNA is likely to be sequenced in all samples. B. The sequenced DNA will be the same from cell type to cell type. C. Unsequenced DNA regions were likely bound to nucleosomes. D. Unsequenced DNA is likely part of euchromatin.

Which of the following statements about chromatin immunoprecipitation is FALSE? A) An antibody that recognizes DNA is used B) It can identify DNA sequences that a protein of interest binds to C) It can be followed by sequencing of the DNA, which is then called ChIP-seq D) Sonication is used to break up the DNA into shorter fragments
