## Chemistry

(see Category:Chemical databases)## Biology

(see: Biological databases)### Bioinformatics

(see: Category:Bioinformatics databases)- EST Assembly - Expressed Sequence Tag. Repository of assembled transcript sequences from the contigation in order to discover new genes from already existing data.
