DNARegion
DNARegion is a term used in genomics to denote a specified interval of DNA defined by a start and end coordinate on a reference genome. Unlike a single gene or transcript, a DNARegion can encompass any contiguous sequence that researchers designate for study, including functional elements, structural features, or arbitrary windows for analysis. Coordinates are typically defined relative to a reference assembly and may be strand-specific or strand-agnostic depending on the context.
Common DNARegion types include coding regions (exons), noncoding regulatory regions (promoters, enhancers, silencers), intragenic regions, replication
DNARegion data are often stored in standard formats such as BED or GFF/GTF, which encode chromosome, start,
Limitations include ambiguity in defining precise boundaries for regulatory elements, alignment issues in repetitive regions, and
Relation to genes and loci: a DNARegion may overlap a gene, span multiple genes, or lie in
