Document Summary

Nurture: everything else that is not genetic: exposure to external factor (pollution, smoking) To date, most researchers believe we are the result of both. There is an interaction between nature and nurture: they influence and affect each other, ex. Nurture stimulates him to the best of his abilities but; there will always be a cap put on him by nature: ex. Different diet (nurture) influences the development of different behavior. In every cell, will the exception of eggs and sperm there are 46 chromosomes. Gene complexes: a large quantity of genes involved in producing a certain character trait: ex. Obesity is linked / associated with numerous genes. Genes are made from nucleotides: adenine, thymine, cytosine, guanine. Genes always pairs in a healthy person. Nucleotides are the alphabet of life: a t, g c. Sequence of nucleotides determine the function of a gene. Analogy: chromosomes -> books, genes -> words, nucleotides -> letters. Human genome: 20 000+ human genes.
