Nucleic acids Sequence sites, features and motifs Nucleic acid sites, features and motifs Nucleic acid functional sites Nucleic_acid_sites_features_and_motifs Sequence tagged sites are short DNA sequences that are unique within a genome and serve as a mapping landmark, detectable by PCR they allow a genome to be mapped via an ordering of STSs. 1.8 Nucleic acid sequence features Primer binding sites The biology, archival, detection, prediction and analysis of positional features such as functional and other key sites, in nucleic acid sequences and the conserved patterns (motifs, profiles etc.) that may be used to describe them.
