昆虫分子生物学的一些研究进展：生物钟的基因

昆虫分子生物学的一些研究进展：生物钟的基因翟启慧（中国科学院动物研究所北京１０００８０）生物的许多行为和生理现象有周期性波动，称为生物节律或生物钟。长期以来，这是一个十分吸引人却又难以理解的问题。虽然有大量文献描述生物钟的现象，但对其机理却一无所知。...

SOME ASPECTS OF PROGRESS IN INSECT MOLECULAR BIOLOGY: BIOLOGICAL CLOCK GENES

This review deals with the progress in the molecular study on the biological clocks in insects. Biological clocks represent a type of cellular regulation common to most eukaryotes. They are disturbed by certain mutations in insects. The genes defined by certain of these mutations in Drosophila have been isolated. The mostimportant clock gene period has been studied in detail, including its structure, expression, regulation, etc. These investigations are revealing the molecular nature of biological clocks.
