BIOLOGIA VEGETALE E BIOLOGIA ANIMALE - BIOLOGIA MOLECOLARE A - L

Learning Objectives

• Plant and animal biology

  Knowledge and understanding: the course provides the tools to describe the fundamental biological structures and processes of the cell and living organisms using appropriate scientific terminology;

  Ability to apply knowledge and understanding: the student acquires the skills necessary to understand the importance of variability so that we can distinguish and motivate the difference between living organisms;

  Learning skills: the student becomes able to use the knowledge on the basic mechanisms that regulate living matter and living organisms (animals and plants) as a substrate for the study of Molecular Biology and of other biological subjects in their Degree Course;

  Making judgments: the student develops his critical ability to evaluate the implications and results of innovative discoveries in the field of cell biology and living organisms. The student is encouraged to follow innovative discoveries in cell biology and living organisms by consulting the scientific literature.

• Molecular Biology

  Theoretical skills of the main biological processes at the basis of the maintenance of the genetic information e its expression in microorganisms and animals.
  Theoretical knowledge of the bio-molecular basic methods supporting the experimental approaches.

Course Structure

• Plant and animal biology

  The course will be structured in frontal teaching with power point projection and/or short films. During the course there will be exercises and problem based learning. Should teaching be carried out in mixed mode or remotely, it may be necessary to introduce changes with respect to previous statements, in line with the programme planned and outlined in the syllabus.
