Create a DNA sequence, complement and transcribe it:
>>>importhaem>>>dna=haem.DNASequence("ACGT")
>>>dna.complement<DNASequence: TGCA>>>>dna.transcribe()
<RNASequence: ACGU>Create an amino acid from a codon and from an ambiguous codon:
>>>haem.AminoAcid("UCA")
AminoAcid.SERINE>>>haem.AminoAcid("UCN")
AminoAcid.SERINE
