GENETICS AND GENETIC IMPROVEMENT OF AGRICULTURAL PLANTS A - LModule GENETICS
Academic Year 2022/2023 - Teacher: Giancarlo RAPPAZZOExpected Learning Outcomes
The Genetics module aims to provide the fundamental knowledge of classical and molecular genetics by providing a framework consistent with the teaching of the other planned module of the I.C. and with the other biological courses envisaged by the Degree in Biotechnology.
The student in Biotechnology, with the didactic module of GENETICS acquires the knowledge of Mendelian analysis methods and understands the mechanisms by which Mendelian characters are inherited and learns to apply them for solving genetic problems. You acquire basic knowledge about the structure of genetic material and its organization, as well as the general principles of gene expression. The student knows the main methods of analyzing DNA and its polymorphisms, and understands that many molecules involved in the main genetic processes are widely used in biotechnology. It includes the characteristics of the different types of mutation, the related phenotypic effects, the main mechanisms of spontaneous DNA mutation and its meaning also in the context of evolution. Students at the end of this course will have to be able to effectively communicate biological information, and genetic information in particular, with a specific language.
