Document Summary

What are genes and how do behavior geneticists explain our individual differences. Every cell nucleus has genetic codes for your entire body. 46 chromosomes= 23 chromosomes from mother"s egg and 23 chromosomes from fathers spem. Each chromosome is contained of a coiled molecule. Chromosome: threadlike structure made of dna molecules that contain the genes. Dna: a complex molecule containing the genetic info that makes up the chromosomes. Genes, small segments of the dna: the biochemical units of heredity that make up the chromosomes; segments of dna capable of synthesizing a protein. Environmental events turn on certain genes; just like hot water allows tea bag to infuse flavour. When a gene is turned on it provides the code for creating protein molecules (body"s building block) In terms of genetics every human is your identical twin. Human genome researchers have found out the common sequence within human dna. In fact we share about 96 percent of our dna sequence with chimpanzee.
