|MODULES||This unit is a module of:|
The participation in the planned educational activities (lectures) will allow the student to acquire the knowledge necessary to understand the molecular mechanisms underlying the strategies of adaptation to living conditions in different marine environments. Specifically, the student will be able to: acquire knowledge on the modalities of expression of genes related to adaptation to abiotic variations of the marine environment. Know the structural aspects of proteins involved in the transport of oxygen and CO2 in fish and marine invertebrates. The management of hypoxia. Know the molecular mechanisms and structural characteristics of proteins and enzymes involved in the production of light in marine organisms Know the main biosynthetic ways for the production of colors in marine organisms Know the cellular and molecular mechanisms underlying biomineralization processes in marine organisms Know the cellular and molecular mechanisms underlying the production of the extracellular matrix of marine organisms Know the molecular and cellular mechanisms underlying chitin metabolism in marine invertebrates To know the molecular adaptations of the organisms that live in extreme environments (chemiosynthesis, the organism-symbiont molecular relationships). The acquisition and understanding of this knowledge will allow the student to be able to deal with the general themes of the development and conservation of marine biodiversity also with a view to global changes and the anthropic impact on the marine environment
The teaching consists of lectures delivered through multimedia presentations.
