Write a method that accepts a string representing a sequence of DNA. You are supposed to either find the matching DNA base-pairs, or find the transcribed RNA. If the value of the Boolean variable 'transcribe' is false, return the matching DNA base-pairs, while if 'transcribe' is true, return the sequence for the transcribed RNA). Look at the test data for examples. Note: DNA Base-pairing rules A-->T and T-->A, G-->C and C-->G; RNA Base-pairing rules A-->U and T-->A, G-->C and C-->G.
