Document Summary

Lecture 3: genes and behavior: process of phenotypic development, chromosome with a gene, rna polymerase that cuts it to produce rna, then it will go to other places like a ribosome to produce protein. For example, transcription factor: genes affect the transcription of other genes (turns some on and off) some are only transcribed at certain points in your life. In order for a gene to have effect, it needs to be transcribed. (nature needs nurture to be transcribed: the way the env. Has its affect is by affecting the transcription factors and polymerase. Has nothing to turn on and off: phenotype = gene + environment (this interaction is development) Intro to dna transcription: behavioral phenotype: a) gene + environment cause brain development; b) brain + Environment produce internal response; c) response causes observable behavior; d)consequences + brain cause learning (change in brain for next time period: env. Triggers gene expression to cause a process you call development.
