Cellular and Molecular Biology 2

This compulsory UE in S3 enables students to consolidate and deepen the foundations of molecular and cell biology acquired in L1.

Molecular Biology part: The molecular and structural bases of nucleic acids will be developed and deepened to understand the physicochemical properties of nucleic acids, which open up various prospects for technological applications, and the molecular mechanisms of the main steps in Molecular Biology, such as DNA replication, transcription of genes into mRNA and translation of these into proteins. These steps, illustrated by experimental evidence deduced from various historical studies, will be studied in depth in prokaryotes. Comparisons with eukaryotes will also be discussed. The molecular mechanisms of DNA repair will also be described and developed.

Cell Biology section: This section covers the major concepts of membrane and cytosolic protein complex formation, particularly in the context of cell signaling pathways. The notions of ligands, receptors, scaffolding proteins, enzymatic signaling proteins, intracellular second messengers and response kinetics will be presented. Biochemistry and cell biology techniques for demonstrating the presence and localization of proteins in cells and tissues will be presented.
