Anotace

čeština

Tento kurz genetiky je určen pro magisterské studenty Programu Parazitologie a infekční biologie. Předpokládají se předchozí základní znalosti z genetiky a molekulární biologie, které budou během semináře zopakovány. Studentům bude poskytnuta „první pomoc“ (v případě potřeby). Seminář je nedílnou součástí kurzu. Řešením teoretických úloh, diskusí a pozorováním mikroskopických vzorků lépe pochopíte probíranou teorii.
Jako doplněk i informacím o genetice modelových organismů budou zmíněny specifické rysy genetiky parazitů a jejich vektorů.
Na konci kurzu získáte dobré znalosti z přenosové genetiky, cytogenetiky a porozumíte principům genomové analýzy a molekulární taxonomie.

Kritéria hodnocení:
Pro získání zápočtu je nutné:
Pravidelná účast na seminářích (minimálně 60%)

This course of genetics is designed for master students of Parasitology and Infection Biology. The previous basic knowledge of genetics and molecular biology is expected and will be revised during seminar. The“first aid“ will be given for students (if needed). Seminar is an integral part of the course. By solving theoretical tasks , discussions and by examining microscopic samples, you get enhanced knowledge of genetics.
Specific features of genetics of parasites and their vectors will be mentioned to complete information based on analysis in model organisms.
At the end of the course you get good knowledge of transmission genetics, cytogenetics and you will understand the principles of genome analysis and molecular taxonomy.



in 2025/26 Lectures: Monday, 9:00-10:30 and seminars: Wednesday, 14:00-15:30
