This text explores genetic changes and conditions, highlighting significant discoveries by Gregor Mendel and the impact of the Human Genome Project. It discusses inherited genetic disorders like Down Syndrome and Cystic Fibrosis, emphasizing their characteristics and implications for health. The role of genetic engineering in manipulating organisms and its applications in various fields, including agriculture and health, is also examined. It addresses both the benefits and concerns surrounding genetic engineering in society.

Genetic Conditions • Down Syndrome • Down syndrome is a genetic condition in which a person has 47 chromosomes instead of the usual 46 • Cystic Fibrosis • a disease passed down through families. • causes thick, sticky mucus to build up in the lungs, digestive tract, and other areas of the body. • It is one of the most common chronic lung diseases in children. • Allderdice Syndrome • A local genetic condition (Sandy Point, in the West Coast of NL) • Identified by Dr. Penny Allderdice at the Health Sciences Center, Memorial University of Newfoundland.
Studying Genetic Changes • Gregor Mendel • Mid-1800s • Experimented with inherited traits in pea plants.
Studying Genetic Changes cont… • Francis Crick & James Watson • 1953 • Described the structure of DNA and how it replicates. • Proposed the double helix structure.
The Human Genome Project • Genome: consists of the full set of genetic material that makes up an organism. • Made a map to identify genes • This information may be used to check for particular diseases. (ex. Allderdice Syndrome) Human Genome Project 1986-2003
Genetic Engineering • Human manipulation of an organisms genome using current DNA technology • Alters the genetic makeup of an organism • Has applications to many areas including the food we eat and issues related to health. • This has led to many concerns and fears both inside and outside the scientific community.
Genetic Engineering in Newfoundland & Labrador • Aqua Bounty Farms • Focused on health and productivity applications in aquaculture • St. John’s, NL
Journal Reflection Activity • Please read and reflect on the genetic engineering article your teacher will give you. • Here is a link to the online copy of the article! • http://greenbio.checkbiotech.org/news/genetic_engineering_makes_apples_more_environmentally_friendly In your reflection be sure to include the following: - What is your view point on genetic engineering? - Do you think genetic engineering has more positive or negative impacts on humans and the planet? - What are some of the positive and negative impacts of genetic engineering?
