The percentage of guanine (G) and cytosine (C) bases in the sequence or its selected region, for example:
GC-content("ACGTAC") = ((0 + 1 + 1 + 0 + 0 + 1) / 6) * 100% = 50% |
If the sequence contains degenerate base characters, average values are used, for example:
GC-content("ACGNBCT") = ((0 + 1 + 1 + 1/2 + 2/3 + 1 + 0) / 7) * 100% ~= 59.52% |
In this example "1/2" is used for "N" (any nucleotide), "2/3" us used for "B" (that means "C", "G", or "T" according to the IUPAC notation).
