sequence classification algorithms can be used to determine whether

• a DNA sequence is part of a gene-coding or a non-coding region,

• identify the introns or exons of a eukaryotic gene sequence,

• predict the secondary structure of a protein, or

• assign a protein sequence to a specific protein family
