OriDB, the DNA replication origin database updated and extended.

OriDB (http://www.oridb.org/) is a database containing collated genome-wide mapping studies of confirmed and predicted replication origin sites.

Control of gag-pol gene expression in the Candida albicans retrotransposon Tca2.

Background: In the C. albicans retrotransposon Tca2, the gag and pol ORFs are separated by a UGA stop codon, 3' of which is a potential RNA pseudoknot. It is unclear how the Tca2 gag UGA codon is bypassed to allow pol expression.
