The Gene Explorer

This application is an interactive simulation of gene expression that allows the user to: The figure above shows the Gene Explorer display: Any changes to the DNA are immediately reflected in changes in the other sequences as appropriate. The software computes the different sequences as follows:
  1. Starts with a DNA sequence.
  2. Finds the promoter (TATAA).
  3. Transcribes the pre-mRNA until it reaches a terminator (GGGGG).
  4. Removes the introns from the pre-mRNA (GUGCG......CAAAG).
  5. Adds a poly A tail.
  6. Translates the mature mRNA from the first AUG to the stop codon.
