Quick example

Executing this:

from Bio.Seq import Seq,translate
 
#create a sequence object of some DNA
my_seq = Seq('CATGTAGATAG')
 
#print out some details about it
print 'seq is %i bases long' % len(my_seq)
print 'reverse complement is %s' % my_seq.reverse_complement().tostring()
 
#or see the whole record
print 'sequence record:', my_seq
 
#translate the sequence into a protein
my_protein = translate(my_seq)
 
print 'protein translation is %s' % my_protein.tostring()
print 'protein record:', my_protein

Produces:

seq is 11 bases long
reverse complement is CTATCTACATG
sequence record: Seq('CATGTAGATAG', Alphabet())
protein translation is HVD
protein record: Seq('HVD', HasStopCodon(IUPACProtein(), '*'))
