Perl Challenges
| 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 |
