General Information
Term eggshell chorion gene amplification ID (Ontology) GO:0007307 (Gene Ontology)
Definition Amplification by up to 60-fold of the loci containing the chorion gene clusters. Amplification is necessary for the rapid synthesis of chorion proteins by the follicle cells, and occurs by repeated firing of one or more origins located within each gene cluster.[ PubMed:11157771 ]
