Anotace

Poslední úprava: Mgr. Michal Štefánek (24.05.2023)

This course will be held in English.
Transposable elements (TEs), since their discovery, have been considered either as useless pieces of DNA, as
selfish parasitic genes or as major elements driving biodiversity. The aim of this course is to bring a holistic
knowledge of TEs, from the molecular mechanisms underlying their function to their impact on populations and
species in eukaryotes. It will involve lectures gathering current research issues as well as practicals involving
modern tools used in current research.
