Welcome to ChromDB

Three types of sequences are included in the database: genomic-based (predominantly plant sequences); transcript-based (EST contigs or cDNAs for plants lacking a sequenced genome); and NCBI RefSeq sequences for a variety of model animal organisms. The Gene Record Page for any sequence indicates the type of sequence. Click on the names of the organisms presented below to see examples of these sequences.

Genomic-based Transcript-based RefSeq-based

Meet ChromDB staff member Cassie Heinle

Cassie joined the ChromDB staff as an undergraduate assistant while pursuing her Bachelor of Science degree in Molecular and Cellular Biology at the University of Arizona. We are fortunate to have her join the staff after her recent graduation. As part of her many duties on the bioinformatics team, Cassie is using Camtasia sofware to develop tutorials to aid users in understanding the website concepts and tools. Her first tutorial introduces concepts associated with our database identifiers. Please click on the "ChromDB Identifiers" to learn more about this important concept.
