Document Summary

Lies along a continuum and are not independent. Genetics influence the brain, and so, a change in the brain function causes a change in behaviour. 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. 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. Chromosomes: structures in the nucleus of a cell that are lined with all the genes that are inherited by a person.
