Mapping the Human Genome

Jessica is learning about the Human Genome Project as part of her genetics unit in 7th grade Life Science.

She watched a clip from the NOVA film "Cracking the Code of Life." Check out this movie here: http://www.pbs.org/wgbh/nova/body/cracking-the-code-of-life.html

Here she summarized some very complex scientific information:






The Human Genome Project

The Human Genome Project was designed to complete the following goals:
¨     Identify all the approximately 20,000-25,000 genes in human DNA,
¨     Determine the sequences of the 3 billion chemical base pairs that make up human DNA,
¨     Store this information in databases,
¨     Improve tools for data analysis,
¨     Transfer related technologies to the private sector, and address the ethical, legal, and social issues (ELSI) that may arise from the project.
Researchers studied genetic makeups of organisms. This was the first big scientific experiment to address potential ELSI implications from project data. A genome is all the data in an organism, including it’s genes. DNA is made up of four chemicals; adenine, guanine, thymine, and cytosine. The order of the As, Ts, Cs, and Gs is very important. Knowledge about DNA leads to ways how to diagnose, treat, and someday prevent thousands of disorder and diseases that affect us.
