Introduction to Biomolecules
Course Objectives :
The course aims to enable the learners to understand the basic processes which link the biological systems with the chemical systems and to provide them with the basic knowledge and insight about the three-dimensional (3D) structure of macromolecules (protein and nucleic acids) and the relationship between their structure and function.
