skbio.sequence.DNA.reverse_complement#

DNA.reverse_complement()[source]#

Return the reverse complement of the nucleotide sequence.

Returns:

NucleotideMixin: The reverse complement of the nucleotide sequence. The type and metadata of the result will be the same as the nucleotide sequence. If positional metadata is present, it will be reversed.

Notes

This method is equivalent to self.complement(reverse=True).

Examples

>>> from skbio import DNA
>>> seq = DNA('TTCATT',
...           positional_metadata={'quality':range(6)})
>>> seq = seq.reverse_complement()
>>> seq
