Study course description
Preliminary Knowledge:
Knowledge of biology acquired within the framework of general secondary education.
To make understanding about molecular processes in cell, linkage between cell function and provision of homeostasis in human body, as well as understanding about principles of human genome structure and role of disturbances in genome in etiology of genetic pathologies, to develop skills of students in work with methods of molecular biology, to help to understand the use of theoretical knowledge in medical practice, to help to understand role of science in medical development and use of scientific opinion in practice of a medical doctor.

Unaided Work:
In the 1st semester: independent acquisition of the topics Structure of cytoplasm of the eukaryotic cell, the structure and functions of organoids. In each lesson, according to the topic, the student receives assignments for independent learning. Task solutions must be used genetic code, its properties. Preparation of presentations in 1st semester about Organelles of eukaryotic cells and their function. 2nd semester about multifactorial diseases in accordance with the criteria discussed during classes.
Assessment Criteria:
Participation in classes and compliance with methodology during laboratory works; weekly tests of theoretical knowledge, ability to explain the results obtained during practical works and to draw conclusions based on the results mentioned above. In the 1st semester the students' knowledge and skills will be evaluated during colloquia: • 1st colloquium: a control class in cytology I (a written theoretical part); • 2nd colloquium: a control class in cytology II (a written theoretical part and solution of tasks). In the 2nd semester the students' skills and knowledge will be evaluated during 2 colloquia: • 1st colloquia: about classification of types of inheritance (a written theoretical part and solution of tasks); • 2nd colloquium: a control class about chromosomal pathology, gene action in population (a written theoretical part and solution of tasks). The following skills will be evaluated: ability to present the prepared material in accordance with the theme and ability to apply theoretical knowledge in solving genetic tasks. A written examination at the end of the course. The examination consists of the themes covered during only 2nd semester. Cumulative assessment of the examination: assessment of colloquia.

Learning Outcomes
Knowledge:• Students analyse the conformity of eukaryotic cell structure with its functions; • justify interrelation of the cell structure and the role of abnormal function in human pathology; • compare processes in mitosis and meiosis; • know the main conformities of genetics; • evaluate the role of Mendel's experiments in the development of genetics; • compare the results of monohybrid, dihybrid, polyhybrid and analytic crosses; • explain types of interaction of allelic and non-allelic genes and impact of interaction on the manifestation of features in phenotype; • analyse the interconnection between genes; • know the primary and secondary structure of nucleic acids; • explain the replication, transcription, translation of DNA and regulation of gene expression; • recognise chromosomal pathologies, analyse possible mechanisms of origin and consequences; • distinguish factors of disarrangement of gene balance in population, know the types of selection and describe the selection in human population; • explain the application of genetic cognitions in medical practice; • justify the manifestations of mutations of development genes in early stages of onthogenesis; • explain the impact of development genes on the formation of the human body; • defend the opinion while analysing particular situations regarding inheriting of human features; • apply conceptions and terms discussed during classes.
