300394 VO Introduction to molecular techniques (2016W)

Combining morphology and molecular biology techniques is vital for thorough studies of diverse biological processes. Recently, genome sequencing provided us with new sets of phylogenetic information and allowed investigation of how the activity of individual genes is regulated. Different analyses based on switching particular genes on or off in particular places in the organism or in cultured cells gave crucial insights into their function. At present, biology is able not only to describe a structure or a process, but also to understand how this structure came to be and what genes were regulating its development.
The goal of this course is to give an overview of the routine molecular methods used in the modern zoology and developmental biology studies. The course is aimed for the Bachelor students of all curricular directions and for the Master students specializing in non-molecular aspects of zoology.
