This course is an introduction to that theory with special emphasis on evolution. A BIO Molecular Biology 3 Mechanisms of gene expression and regulation will be studied, using examples from bacteria and eukaryotes. These techniques are used to investigate cell motility, membrane structure and permeability, mitochondrial respiration, DNA replication, the cell cycle, and cell adhesion.

One laboratory per week, plus additional flexible time as required. The potential of modern genetic techniques to provide diagnosis and treatment of diseases will major difference between sex determination in drosophila and humans in Албани be discussed. These electrical signals are recorded from the nervous systems of cockroaches, crayfish and fruit flies; the signals are examined using data acquisition and analysis software.

Feature extraction will be considered as the basis of visual localization and prey insect capture in toads and in echo localization and insect capture in bats.
