One of the five teachers trained went on
to use BW with her students and
became a local BW trainer.

Tutorials are well designed and provide practice in the skills needed to analyze gene and protein sequences. Genetics Analysis and Cell Physiology Sickle Cell Anemia is a good first tutorial. The Cystic Fibrosis tutorial is more complex and should be used after SCA. Make hard copies of the instructions so students are not impeded by clicking back and forth between the instruction screen and the tutorial screen.
Comparison of nucleic or amino acid sequences of various organisms provides a means of finding evolutionary relationships. see above The SRS Database Search allows students to find the protein product corresponding to a genomic sequence. Afternoon access was much slower than morning access.
Protein alignments enable the construction of phylogenetic trees. see above The CLUSTAL_W function allows multiple sequences to be aligned. When searches for some proteins were unsuccessful, students were directed to search for other proteins so they could master the Clustal_W function.
