Introduction to molecular genetics: chromosome structure, genetic code, DNA replication mechanisms, transcription, RNA processing, translation. Principles of gene expression, DNA – protein interactions, gene targeting, control of gene expression, eukaryotic gene regulation, recombinant DNA and genomes. Genetic load, Genetic selection (Selection types, Speciation, species interactions), Genetic diseases. Quantitative Genetics, Genomics (Structural, Functional), gene identification, gene function determination, analysis of gene expression. Comparative genomics. Population Genetics, Molecular Ecology (molecular genetics applications for evolution, ecology and behavior issues), Genetic indicators and modern methods of detection. PCR, Sequencing (Classic and ‘New Generation’). Applications of Genetics in the Marine Environment: Physiology and evolutionary history, molecular taxonomy and barcoding techniques, assessment of diversity in marine communities / assemblages, population genetics and phylogenetics, genetic applications for the protection of species and marine ecosystems (Conservation Genetics) applications of genetic analyzes in the study of biological invasions, biomarkers – environmental control and monitoring, genetics and aquaculture (farmed marine species), genetics / genomics of the marine environment, metagenomics, metabarcoding.
