1.) The ultra sequencing I've recommended specifically searches for and reports on individual mutations including both coding and non-coding regions.

2.) DNA, as I assume you meant DNA, is the substrate for epigenetic regulation, and changes in the epigenetic marks on DNA can influence the expression of specific genes and have an impact on an individual's traits and susceptibility to certain diseases. Via high-throughput whole genome NGS, the ultra sequence also provides parsable insight into the epigenome.
