gcContent method

double gcContent()

Returns the percentage of Guanine and Cytosine nucleotides in this sequence.

Implementation

double gcContent() {
  int gcCount = 0;
  this.seq.split('').forEach((nuc) {
    if (nuc == 'G' || nuc == 'C') {
      gcCount++;
    }
  });
  return double.parse(
    ((gcCount / this._len) * 100).toStringAsFixed(2),
  );
}
