'''
DNA is a double-stranded molecule containing two complementary strands. 
To make an mRNA, a part of a DNA strand is transcribed. The resulting mRNA has
nucleotides complementary to the DNA template (note: RNA contains uracil 
instead of thymine).

Exercise: Pseudocode

For each of the exercises below, start by writing 
pseudocode on a piece of paper. Only once you're done with pseudocode should 
you start working on Python code in VS Code.
'''

'''
Exercise A: DNA strands

Find the strand complementary to the given DNA strand.
Note that the input DNA string may *not* be only made of A, T, G, and C.
The program should be able to handle this: represent a failed match as an X.

Store the output string in DNA_complement variable.

'''
Exercise B: Transcription

Transcribe the given DNA sequence into an mRNA sequence.
Note that the input DNA string may *not* be only made of A, T, G, and C.
The program should be able to handle this: represent a failed match as an X.

Store the output string in mRNA variable.

'''
Exercise C (Bonus): Match-case

Do the same as in Exercise B, but use match-case.
