The NCBI Assembly Archive links the raw sequence information found in the Trace Archive
with assembly information found in publicly available sequence repositories (GenBank/EMBL/DDBJ).
The Assembly Viewer allows a user to see the multiple sequence alignments as well as the actual sequence chromatogram.
