PSYA01H3 Chapter Notes - Chapter 3: Trisomy, Cerebral Cortex, Human Behaviour
Document Summary
Lies along a continuum and are not independent. Hereditary & behaviour: behaviour are influenced by genes, genetics influence the brain, and so, a change in the brain function causes a change in behaviour. The genetic code: our genetic material is organized into genes. Genes: the basic units of heredity; genes guide the process of protein synthesis that makes up our physical structures and regulates development and physiological processes: genes are made up of segments of dna. Dna (deoxyribonucleic acid): double helix shaped molecule that contains 4 nucleotides: adenine, thymine, guanine, cytosine, each gene is a unique combination of the 4 nucleotides genotype. Genotype: the genetic makeup of an organism: the sequence represents a code that instructs cells to make certain proteins phenotype. Phenotype: the physical traits or behavioral characteristics that show genetic variation: phenotypes arise due to the differences in the sequence of nucleotides, genes are organized in pairs along chromosomes.
