GENETICS AND INTEGRATED BIOTECHNOLOGIES LABORATORY I
Learning outcomes of the course unit
To provide the first year students with the basic concepts of classical and molecular genetics
Course contents summary
The cours is composed of two main section. 1.CLASSICAL GENETICS: Mitosis and meiosis. Mendelian genetics. Characters segregation. Independent assortment. Modification of mendelian ratio. Multiple alleles. Gene interaction. Genes on X chromosome. Chromosome theory of inheritance. Linkage and recombination. Crossing over. Recombination in yeast. 2.
MOLECULAR BASIS OF HEREDITY: Events leading to the acceptance of DNA as genetic material. DNA: structure and replication. Chromosome structure in prokaryotes and eukaryotes. RNA structure, transcription and translation. The genetic code and its deciphering. Gene structure and organisation. Interrupted genes. The one-gene: one-enzyme hypothesis. Analysis of biochemical pathways. Genic complementation. Gene expression. Genome, chromosome and gene mutation. Molecular basis of mutation. Reversion. Suppressio. Detection of spontaneous or induced mutants. Regulation of gene expression in prokaryotes. Operon Lac: negative and positive control; operon Trp: repression and attenuation; feedback regulation.
Practical and theoric activities are supporting the lessons.
