6.4 Studying Genetic Changes Student text p

 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.

 Gregor Mendel ◦ Mid-1800s ◦ Experimented with inherited traits in pea plants.

 Francis Crick & James Watson ◦ 1953 ◦ Described the structure of DNA and how it replicates. ◦ Proposed the double helix structure.

 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

 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.

 Aqua Bounty Farms ◦ Focused on health and productivity applications in aquaculture ◦ St. John’s, NL
