Introduction to the Biology. Cell theory: cell and organisms. Structure and function of the proteins: primary, secondary, tertiary and quaternary structure. The enzymes. Structural and functional organization of eukaryotic and prokaryotic cells. Organelles: structure, function and evolution. Smooth and Rough reticulum, the Golgi apparatus, the lysosomes and peroxisomes.Viruses. The Metabolism and the energetic bases of the vital phenomena: the functions performed by ATP. Cell membranes: structure and function. The Endocytosis and Exocytosis. Membrane Fluidity. Role of membrane phospholipids and cholesterol. Intrinsic and Extrinsic protein. Glycoproteins and Glycolipids. The mechanisms of transport across the membrane: simple and facilitated diffusion. The active transport. Signal Transduction. The Hormones.The G-coupled receptors. Role of AMPc . Mechanisms of interaction between cells: CAM (Cadherins and Integrins). The genetic information : The nuclear genome: structure and function.The DNA structure: the double helix of Watson and Crick. Chemical composition of DNA. Chargaff Rules.The DNA in prokaryotes: the bacterial chromosome. The DNA in eukaryotes: Chromatin and chromosomes. The central dogma of molecular biology. From genotype to phenotype. Phenotype and environment. DNA replication: molecular mechanisms. Replication of telomeres: Telomerase. Polymerase Chain Reaction (PCR): technology and its implications for Medicine. Expression and biological functions of the genome. Classification and structure of eukaryotic and prokaryotic genes. The process of transcription in prokaryotes and eukaryotes: synthesis and processing of RNA [mRNA and non-coding RNAs (ncRNAs) including the miRNA]. The Splicing. Post-transcriptional RNA processing. Regulation of gene expression in eukaryotes. The Genetic Code. Protein synthesis. The Cell Reproduction: Cell division: binary fission, mitosis and meiosis. Male and female gametogenesis.The human karyotype: normal and pathological karyotypes. Numeric chromosomal abnormalities: trisomies and monosomies. Mitotic and meiotic non-disjunction. Mosaicism. Cell Cycle and CancerCell proliferation: the cycle and related control mechanisms. The neoplastic phenotype: Oncogenes and Tumor suppressor genes. Apoptosis.
