Translating DNA into protein
============================

.. sectionauthor:: Gavin Huttley

To translate a DNA alignment, read it in assigning the DNA alphabet. Note setting ``aligned=False`` is critical for loading sequences of unequal length. Different genetic codes are available in ``cogent3.core.genetic_code``

.. doctest::

    >>> from cogent3 import load_unaligned_seqs
    >>> al = load_unaligned_seqs('data/test2.fasta', moltype="dna")
    >>> pal = al.get_translation()
    >>> print(pal.to_fasta())  # doctest: +SKIP
