Problem	Input	Output
DNA transcription	A DNA sequence, in 5'-3' direction (e.g., aaatttaaaagacaaaaagactgctctaagtcttgaaaatttggttttcaaagatgat)	An RNA sequence, in 5'-3' direction
Genetic code	None	64 codons, one per line (using loops)
Random sequence 1	None	Generate a random DNA sequence (e.g., 1000 bases) with equal base frequencies
Random sequence 2	None	Generate a random DNA sequence with biased base frequencies, e.g., 10% G, 10% C, 40% T, and 40% A.
Graphics I	a categorical dataset, e.g., Biology	a bar graph & a pie char, using GD::Simple or Postscript::Simple
