Learning outcomes

The aim of this course is to give the students the basic knowledge of the molecular mechanisms concerning transmission, variation and expression of the genetic information.

Syllabus

-> Genetic information and informational molecules
General introduction and historical hints. The chemical structure of DNA and RNA. Three dimensional structure of DNA. Physico-chemical properties of DNA.
-> DNA, RNA and gene structure
Definition of gene coding and regulatory regions. From genes to proteins; messenger RNA, transfer RNA and ribosomal RNA.
-> Genome organization and evolution
DNA content and number of genes. Mutations, DNA rearrangement and genome evolution. The organelle genomes. Interrupted genes; introns. cDNA. Gene families and duplication. DNA repeats.
-> Transposable elements 1
Transposition mechanisms and control. Transposons.
-> Chromatin and chromosomes
Nucleosomes, histones and their modifications. Higher organization levels of chromatin. Heterochromatin and euchromatin. Eukaryotic chromosomes, telomeres and centromeres.
-> DNA replication
DNA polymerases. Proofreading activity of DNA polymerases. Replication mechanism in bacteria and eukaryotic cells.
-> Introns and RNA splicing
Features of spliceosomal introns. Spliceosome and splicing mechanism. Alternative splicing and trans-splicing. Other kinds of introns: group I and group II introns and tRNA introns. The intron movement. RNA editing. Ribozymes and riboswitch.
-> DNA mutation and repair
Spontaneous mutations and mutations caused by physical and chemical mutagens. Pre- and post-replicative repair systems. Recombination in the immunity system cells. Approaches to homologous recombination.
-> Regulation of gene expression 1
Eukaryotic promoters. Activators, repressors and coactivators. Gene expression and chromatin modifications. Epigenetic mechanisms.
