  This learning unit is not being organized during year 2024-2025.

  This learning unit is not open to incoming exchange students!

Language
French
Prerequisites
The prerequisites are:
  •     In genetics (genetics and biotechnology): classical genetics, notion of genetic linkage, chromosomal theory, mitosis and meiosis, gene expression (transcription and translation with their molecular mechanism), DNA repair (everything except repair of double-strand breaks)
  •     In biostat (proba and stat): concept of relative frequency, mean and standard deviation, probabilities and independent events, confidence interval at the mean
  •     In biochemistry (chemistry of life): structure of proteins, effects of solvents, enzymatic catalysis
  •     In (general and) organic chemistry: acids and bases, nucleophilic/electrophilic attacks and stereochemistry
  •     In general biology: general structure of cells (prokaryotes and eukaryotes, evolution, molecular evolution, trophic, symbiotic and parasitic interactions

The prerequisite(s) for this Teaching Unit (Unité d’enseignement – UE) for the programmes/courses that offer this Teaching Unit are specified at the end of this sheet.
Main themes
  • The plasticity of genetic information
  • Genetic engineering: molecular biology, transgenesis and genome sequencing
  • Genetic logic and genetic interactions
  • Study of polymorphism for the discovery of associations between genotype and phenotype
Learning outcomes

At the end of this learning unit, the student is able to :

. 1) Mastering molecular processes that stimulate genomic plasticity at the generational scale on the one hand and evolutionary on the other hand
2) Understand the tools of molecular biology and their limits
3) Understand the generation of large DNA sequences and their constraints
4) Integrate genetic logic and concepts of genetic interactions
5) Understand the logic of genetic association from genomic data

Teaching methods
Each chapter is the subject of one or more successive videos. The videos are posted online at the start of the course. The student watches these videos at a time when he/she is receptive, trying to understand the complex mechanisms presented in the course. At regular intervals, question-and-answer sessions, each centered on one or more chapters, are held face-to-face, in a room equipped with a separate whiteboard and video projector. Q&A sessions are not mandatory for the student. At each question-and-answer session, a first part consists of a discussion by group of 4-5 students, first on questions that seem simple, typically vocabulary words or details of mechanisms. The larger questions and unresolved details in the first part are the subject of questions posed directly to the teacher in the second part, where the whole group is brought together.
Evaluation methods
The assessment will be in the form of an oral exam, as long as the number of students is compatible with this type of assessment. The exam begins with a period of 45 to 60 minutes during which the student gathers these ideas and draws diagrams that can help him then present orally (about 15 minutes) an answer to the questions asked. The discussion is an opportunity to cover topics not covered by the questions initially asked. The purpose of assessment is of course to assess the integration of learning outcomes.
