This chapter describes sequencing-based methods for profiling dynamic changes in DNA accessibility and gene expression in Saccharomyces cerevisiae. Assay for transposase-accessible chromatin with high-throughput sequencing (ATAC-Seq) is a powerful technique for identifying nucleosome-free regions of the genome. Combining ATAC-Seq with RNA Sequencing (RNA-Seq) is a rapid approach for studying the relationship between genome structure and changes in global patterns of gene expression from a single experiment. A laboratory protocol is presented for these methods as well as examples of typical results and visualizations.
Keywords: Chromatin; Gene regulation; Genomics; Transcription; Transcription factors.
