inducible system

inducible system
Индукционная система
1. Система, состоящая из организатора и реагирующего материала, где детерминация происходит по типу «расходящихся кругов», т. е. способность к образованию соответствующего органа уменьшается к периферии (см. Становления система).
2. Регуляторная система, при действии которой продукт регуляторного гена (репрессор, см.) является активным и блокирует транскрипцию оперона. Эффектор, называемый индуктором, инактивирует репрессор и инициирует синтез иРНК, т. обр., транскрипция происходит только в присутствии молекул эффектора.
