DNA to RNA

As well as for "reverse strand", the transformation of a string od DNA in a string of RNA is trivial for any biologist. The basic idea is very similar, here the script:


#!/usr/bin/python
import sys
DNA=sys.argv[1]
CODE={'A':'U','T':'A','C':'G','G':'C'} 
RNA=''
for c in DNA:
        RNA=RNA+CODE[c]
print RNA


In comparison of "reverse strand" script, you have to change the cariable CODE contents. Such code is passed in form of dictionary, one of the most virtuous python data structures . Also in this case the script request a DNA sequence as argument.
