7) Programming skills. Design and then write a program called ribosome.py. It should have two functions: one called getAa, which takes three letters and which turns ATG into an "M", (Methionine), the stop codons ('TAA', 'TAG', or 'TGA') into a single period'., and for any other codon should produce a 'X' (shorthand for a default amino acid). The getAa function should be called by a larger, second function called translateDna and return data to it. For example if your code is run with the test code #Test code for translateDNA dna='ATGGGGCCCTGA' protein=translateDna(dna) print "Protein is", protein it should print out: Protein is MXX
