hi Jesus!
Thank you for referencing me to that quiz, its nice to study the code. 
That exactly solves one of the problems that i had while looking for dna 
motifs which are represented as regular expressions, but need to be 
expanded if you gonna use them as possible dna primers. and then such 
back and see which one gives the best predictive value ... blah blah ... 
Sorry for the bio talk :)

Thank you so much!!
