Exercise 1
Read a Fasta File in your current directory and print the complement of the sequence
Exercise 2
List the Standard codon tables available for translation of the nucleotide sequences
Exercise 3
List the Vertebrate Mitochondrial codon tables available for translation of the nucleotide sequences
Exercise 4
