1. Genetic Variations PAGES 75-81 ACA DECA PRESENTATION

2. Genetic Variations among Humans/ Transgenic and Genetically Modified Organism HGP sequences samples of the human genome Humans share 99.9 of their nucleotides. The.01 difference is what gives us our individuality. Half of it from our mom and half from our dad Its what forensics use to identify people just by that.1 Genetic modifications of multicellular organisms The gene can be transferred in the way of microinjection, retrovirus, or transferring embryonic stem cells Humans have been trying to modify other species for a long time. Not just with animals or humans, but also plants to increase agricultural production

3. EPIGENETICS Can genes be influenced by the environment? Chemicals that can modify genes are everywhere in our life Food, medicine, pollutants The chemicals can mostly influence in two ways DNA methylation Histone modification 1. DNA methylation involves the addition of a methyl group(CH3) to the back bone (phosphate-sugar) May interferes with protein 1. This is very bad 2. Histone Basic protein that wraps around and packages the DNA into chromosomes Bind tight or too loose Covers up and turns off or exposes and turns on

4. The Ethical, Legal, and Social Implications of the HGP The fair use of genetic information to prevent misinterpretation and misuse of patients’ genome information The diagnosis and treatment of diseases Ethical The protection of using the information to deny employment or health insurance The diagnosis and treatment of disease Legal The use of pre-implantation and prenatal genomic diagnosis and other genomics-based reproductive technologies The fair distribution of benefits derived from the genome research Social
