Abstract
A method and apparatus are disclosed for identifying protein-coding regions in a nucleic acid sequence. In order to predict the coding regions within a sequence, a single metric is used without reference or comparison to a predetermined noise level or signal-to-noise ratio. This single metric, periodicity at ⅓, is analyzed using a discrete cosine transformation (DiCTion) function. For each open reading frame or sequence region, a score is generated using the discrete cosine transformation function. Regions within a sequence that have a score above a predetermined threshold are identified as protein-coding regions. The aspects of the invention may also be applied to gather other information from sequences, such as the location of the borders of a putative coding region, within a genomic sequence.
