Course detail

Molecular Biology

FSI-TBI Acad. year: 2023/2024 Winter semester

Basic terms of molecular biology. Chemical properties, structure and interactions of nucleic acids and proteins. Methods of biomacromolecules studies, genomics, proteomics, molecular diagnostics. Biosensors, nanotechnology applications in biomacromolecules studies.

Language of instruction

Czech

Number of ECTS credits

5

Entry knowledge

Basics of physics, inorganic, organic and physical chemistry, biochemistry and general biology

Rules for evaluation and completion of the course

The assessment of a student is made upon his performance in practice and quality of a discussion on topics selected at the examination (lecture notes allowed at preparation).
The presence of students at practice is obligatory and is monitored by a tutor. The way how to compensate missed practice lessons will be decided by a tutor depending on the range and content of the missed lessons.

Aims

Educate the students in basics or molecular biology, particularly in properties of nucleic acids and proteins. The emphases will be put to physico-chemical properties of biopolymers and utilization of these properties in bioanalytical applications, biosensors and nanotechnologies.

The course facilitates a choice of a diploma project by a student and provides him/her basic knowledge on molecular biology as well as interdisciplinary themes at frontiers of molecular biology, physical and analytical chemistry, biophysics, nanosciences and biomedical applications.
