This is the standard implementation of the ISequence interface. It contains the raw data that defines the contents of a sequence. Since Sequence uses enumerable of bytes that can be accessed as follows: Sequence mySequence = new Sequence(Alphabets.DNA, "GATTC"); foreach (Nucleotide nucleotide in mySequence) { ... } The results will be based on the Alphabet associated with the sequence. Common alphabets include those for DNA, RNA, and Amino Acids. For users who wish to get at the underlying data directly, Sequence provides a means to do this as well. This may be useful for those writing algorithms against the sequence where performance is especially important. For these advanced users access is provided to the encoding classes associated with the sequence.
