Biological Basis of Behavior William James- mental activity is also physiological activity Neuron- basic unit of the nervous system *Each neuron is a living cell with a nucleus and other parts common to all cells. Three main parts of the neuron: 1. Dendrites: the receiving part of the nucleus 2. Cell body (Soma): The processing part Electrochemical Transmission 3. Axon: the transmitting part Normal habit change: Doing the same behavior over and over again (same neurons being used over and over)

The novel A Hero of our Time by Mikhail Lermontov is a novel based on Russian

THE MOLECULAR BASIS OF INHERITANCE I. History A. Discovery of “transformation” – a change in genotype and phenotype due to the uptake of external DNA by a cell 1. Griffith 1920s did experiments with Streptococcus pneumoniae (p294 fig16.2) a. took two strains of S. pneumoniae‚ one virulent‚ one not b. heat killed virulent strain‚ then mixed them with the living nonvirulent strain c. living nonvirulent strain became virulent d. nonvirulent strain took on virulent strain’s DNA became virulent
