GENETIC
ENGINEERING

By: Leah Palmquist

Outline

Reasons for
Genetic
Engineering

Plants

Economic
efficiency

in agriculture

Increased
nutritional

value

Animals

Livestock

Used as a model
for

human diseases




Genetic Engineering:

any alteration of genetic
material, to make an organism capable of
producing new substances or performing new
functions.



Transgenic: of, pertaining to, or containing a gene or
genes transferred from another species


Plants
-

Economic Efficiency in Agriculture



Corn



-

Key material for a variety of processed foods




-

Major animal feed




-

In growing demand to make ethanol for use in
alternative fuels




-

Biotech companies are working to create a drought
-

resistant strain of corn



Plants
-

Increased Nutritional Value


Rice


400 million people in the world are effected by
vitamin A deficiency



Transgenic strain of rice produces an enzyme which
results in increased synthesis of vitamin A



Genes from the common daffodil and bacterium
Erwinia uredovora

Use of Genetic Modification in Livestock



Cows


Milk with specific characteristics to supply population
deficiencies



* High
β
-
caesin

levels




-

cheese production



* lactose
-
free milk




-

lactose intolerant



* milk without
lactoglobulin




-

allergenic consumers



* human
lactoferrin

protein




-

newborns


Modeling for Human Disease



Fragile
X syndrome


Effects 100,000 people in the United States



Currently no treatment available



Symptoms include mental retardation, epilepsy and
abnormal body growth



Results from the silencing of one specific gene



Genetically Engineered mice were used as test subjects



A drug was found which corrected many symptoms

Ethical Questions



Slippery Slope argument



Christian Standpoint



Essentialist View



Evolutionary view

Slippery Slope Argument


Genetic
Engineering of
plants

is accepted

Genetic
Engineering of
animals is
accepted

Genetic
Engineering of
humans is accepted

Christian Standpoint


God is the creator of each individual, who he made
in his own image. Genetic engineering is seen by
many Christians as “playing God”



So God created man in his own image, in the image
of God created he him; male and female created he
them.

Genesis 1:27



Essentialist View vs Evolutionary View


Essentialist view: Humans are special, and
have the ability to suffer and feel pain while
animals do not.




Evolutionary View: We are not respecting
the animals from which we descended
