- A Quantitative mRNA expression levels that are generally averaged uniformly across an entire population of cells studied closely under usual circumstances
- B Genome-wide open chromatin regions (accessible, active regulatory elements) by transposase-accessible chromatin with high-throughput sequencing
- C Mainly the overall pattern of cytosine methylation occurring across the entire genome of the cell being studied closely according to most researchers
- D Mainly the precise genomic location of repetitive, transposon-derived DNA sequences scattered within the chromatin region in the majority of cases studied
Correct answer: B. Genome-wide open chromatin regions (accessible, active regulatory elements) by transposase-accessible chromatin with high-throughput sequencing
Explanation: ATAC-seq: Tn5 transposase cuts and tags accessible (open) chromatin. Sequencing maps genome-wide open chromatin regions, identifying active promoters, enhancers, and regulatory elements.
