15950 - Biology and Genetics (A)

Learning outcomes

As far as Biology is concerned, the student will learn how to relate the main cell functions with cell structure. The student will know the cellular processes and will acquire competences on their regulation: gene regulation, the main mechanisms of differentiation and cell specification, regulation of motility, cell-to-cell communication, cell cycle and apoptosis regulation. Also in the study of human reproduction enphasis will be on the regulation of the processes. The student will learn how to apply the acquired knowledge to biomedical problems concerning regulation mechanisms and their possible alterations.
As far as Genetics is concerned, the student will acquire the basic concepts pertaining to genetic information and the mechanisms related to its conservation, expression and transmission; the concepts of gene and genoma, of their structure and their function; will know the phenomena related to the different features of character heredity and genetic variability; will know about polymorphisms, mutations, population genetics; will acquire the methodological bases of the use of advanced technologies in molecular genetics and the capacity of applying the acquired information to biomedical problems.

Course contents

The living matter; the properties of living beings; the Central Dogma in Biology; the cellular theory; living beings and environment. Living matter and its organization; the eukaryotic cell; the prokarotic cell; the viruses. Unity and diversity in life: criteria of classification ofliving beings; the evolution and its main steps; biogenesis of cellular organels. Information molecules: the biological role of DNA, RNA and proteins. The chromatin: its structure and its organization. Gene regulation: concept of gene regulation; chromatn and gene regulation; transcriptional, post-transcriptional, translational and post-translational regulation in eukayotic organisms; protein degradation; differentiation. Inner membrane functions and their relationship with the plasma membrane: post-tradunslation modifications of proteins; protein sorting and transport. Cell motility: the cytosketeton and the regulation of cell motility. Cell-to-cell communication: cell-to-cell and cell-to-extracellular matrix commuication and signals. Mitosis and meiosis: molecular, cellular and oganismic duplication and reproduction; biological meaning of cell division; fenomenology of cell division processes. The cell cycle: cell cycle steps; control of cell cycle; apoptosis and cellular senescence. Reproduction of living beings: reproduction and sexuality; parasexual phenomena; sexual and asexual reproduction. Reproduction in the humans:: gametogenesis in the female and in the male and its regulation; the mature gametes; the fertilization.

The student will learn also: to utilize text books, web pages suggested by the teacher and additional material supplied by the teacher to study (and to get a deeper insight on) the different topics of cell biology; to integrate the knowledge acquired in cell biology with those that will be acquired in the course of molecular biology; to study autonomously, in order to deepen the knowledge of some topics; -to study critically, i.e. to compare the knowledge he/she will acquire within different frameworks, since for some sibjects more than a theory will be presented; to have a quantitave approach, and to solve simple problems; to communicate his/her own knowledge with clarity.

Readings/Bibliography

There is no "ideal" textbook for our Biology course, however the Biology section of the following:

-De Leo G, Ginelli E, Fasano S, Biologia e Genetica, EDISES, II ed., with a chapter on the biology of reproduction,

comprises most of materials that will be studied..
