How do I Transcribe a DNA Sequence to an RNA Sequence?

In BioJava DNA and RNA Sequences and SymbolLists are made using different Alphabets you can convert from DNA to RNA using the static method transcribe() in RNATools.

```java import org.biojava.bio.symbol.*; import org.biojava.bio.seq.*;

public class TranscribeDNAtoRNA {

  public static void main(String[] args) {

     try {
      //make a DNA SymbolList
      SymbolList symL = DNATools.createDNA("atgccgaatcgtaa");

      //transcribe it to RNA (after BioJava 1.4 this method is deprecated)
      symL = RNATools.transcribe(symL);

      //(after BioJava 1.4 use this method instead)
      symL = DNATools.toRNA(symL);
      
      //just to prove it worked
      System.out.println(symL.seqString());
     }
     catch (IllegalSymbolException ex) {
       //this will happen if you try and make the DNA seq using non IUB symbols
        ex.printStackTrace();
     }catch (IllegalAlphabetException ex) {
      //this will happen if you try and transcribe a non DNA SymbolList
        ex.printStackTrace();
     }
  }

} ```
