List of functions and usage
seq_percent(dna_sequence,*char)
has_stop_codon(dna,frame=0)
1. compute DNA sequence
def seq_percent(dna_sequence,*char):
sum=0
listed=[]
dna_length=len(dna_sequence)
for arg in char:
if listed.count(arg)==0:
sum= sum + dna_sequence.count(arg)
listed.append(arg)
return (sum)*100.0/dna_length
2. This function checks if given DNA has in frame stop codons.
def has_stop_codon(dna,frame=0):
stop_codon_found=False
stop_codons=['tga','tag','taa']
for i in range(frame,len(dna),3):
codon=dna[i:i+3].lower()
if codon in stop_codons:
stop_codon_found=True
break
return stop_codon_found
