10 Second 54 Lectures Microbial and Molecular Genetics (C.J. Dorman/K. Devine): This course presents an evidence-­‐based description of the basic cellular processes of transcription, translation and DNA replication.

The course covers the major events in transcription initiation, positive and negative control of transcription, coordinated control of transcription, the operon, the regulon, the stimulon, an introduction to global regulation, DNA structure and gene regulation, environmental adaptation through variations in gene expression, stereotypic and stochastic responses, and transposition – insertion sequences IS1 and IS3 Practicals (i) Microbial and Molecular Genetics (C.J.

Practical aspects include the use of reporter gene fusions to detect environmentally-­‐regulated promoters, reporter gene assays, detection of regulatory genes by transposon mutagenesis, marker rescue, characterization of regulatory mutants and complementation tests. The course also covers the application of whole genome analysis methods to the study of bacterial gene expression. (ii) Statistics Tutorials (M. Fares): The main objective of this course is to make students see the need for understanding data analyses as a step preceding the design of new experiments. These tutorials include: 1. Description of main concepts in Statistics including Sampling, descriptive statistics and probability distributions. 2. Probabilities and Probability Distributions. 3. Hypothesis testing. 4. Analysis of Variance. 5. Linearity testing of relationships between variables. 6. Factor variance analysis and re-­‐building of new hypothesis. The course is given in 4 sessions of two hours each and the understanding of the students is examined through a final test, which includes 4 questions. Two of the questions are short answers and the other two consist on developing a problem and unfolding the possible conceptual and statistical solutions. The course is highly active and requires the active participation of the students. This is assured by presenting example problems and by asking students to form groups to address the problem.
