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

1986

2003


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

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?
