Document Summary

Outside factors that do not effect dna. There is an interaction between nature and nurture. Example: down"s syndrome- through nurture, the child can be pushed (not in a bad way) and can improve cognition but nature puts a cap on the cognition abilities still. Example: worker and queen bees- have the exact same dna. When the larva is chosen for queen, they are given different diets and activate different genes in order to complete different actions, like reproduce a large amount of times. 46 chromosomes or 23 pairs in every pair. Guiding manufacturing of proteins in the body. Some genes can result in huge differences. Complex genes- multiple work together- called gene complex: example: obesity. Expressed as nucleotides- biochemical bases- four- a, g, c, t: a- adenine, g- guanine, c- cytocine, t- thymine. People are 99. 99% similar genetically: repartition of 0. 01% differences: Nature genetics 2004: study discounts link between dna, race.
