Document Summary

Genes: segment of dna that produce specific protein, can be turned on and off. Only 10% - 20% of the genes in a particular cell (such us skin cells & brain cells) are active. Agouti gene - it produces yellow fur and obesity in mice when it is turned on. Environmental conditions might turn it on (when pregnant mice ate food contain bpa) Nurture: the result of our interactions with the environment. Francis galton is the founder of the debate "nature vs nurture" Every nucleus in near 37 trillion cells of our bodies contain two complete copies of human genome, the instruction for building a human. Gene - each gene contains instructions for making a particular type of protein. Gene expression occurs when these instructions are used to produce a particular protein (the process of converting genetic instruction into a feature of living cell) it is different in nerve cells and skin cells.
