Persuasion

Biologist may one day be able to use
genetic engineering to alter a child’s inherited
traits. Write a persuasive paragraph expressing
your opinion on the following: Under what
circumstances, if any, should this ability be used?

CH 15 GENETIC ENGINEERING

15.4 Ethics and Impacts of Biotechnology


In the movie GATTACA,
schooling, job prospects,
and legal rights are rigidly determined by an
analysis of the individual’s DNA on the day he or
she is born


Are we moving closer to this kind of society?

Profits and Privacy


Private biotechnology and pharmaceutical
companies do much of the research involving GM
plants and animals to develop profitable new
crops, drugs, tests, or other products.

Patenting Life


Molecules and DNA sequences can be patented


One fifth of the known genes in the human genome
are now patented commercially.


Laboratory techniques like PCR have also been
patented


When you do that test you pay a fee for it


Patent disputes over golden rice kept it from
farmers for years.


How much privacy in terms of your DNA, are you
entitled to?



Do you have exclusive rights to your DNA?



Should you, like patent holders, be able to keep
your genetic information confidential?


To serve in the military you need to provide a DNA
sample to keep on file for identification


Who all can get access to that information and for
what purposes.

Pros of GM Foods


Produce higher yields


Need little insecticide or herbicide to grow


Lower cost


Lower land and energy use


No scientific support for safety concerns.

Cons of GM Foods


No long term studies


Harm beneficial insects


Overuse of insect and weed killing compounds


Price of GM seeds to high to allow small farmers
and farmers in less developed countries to use


No additional testing or label is required for GM
food in the U.S.

Ethics of the New Biology


The same GFP technology was used to create
fluorescent zebra fish



AND fluorescent mice, tadpoles, rabbits, and even cats



Just because we can make these, should we.


Should biologists try to engineer taller people or
change their eye color, hair texture, sex, blood
group, or appearance


What happens if/when we start making clones of
ourselves


What will happen to the human species when we
gain the opportunity to design our bodies or those
of our children?

Survey Biotechnology Opinions

1.
Select two issues for each of the following safety,
legal, ethical issues related to genetic engineering

2.
Design a survey to ask people their opinions on
these issues.

3.
Find 15 people to survey (only five can be in your
class)

4.
Collect surveys and tabulate the answers.

Copy down the following questions to answer after you
complete your survey


1.
Analyze Data

Did all respondents agree on any
issue
-

if so which one(s)

2.
Draw Conclusions

If you had surveyed more
people, do you think you would have found more
or less agreement in the responses
-

why

3.
Evaluate

How informed about biotechnology
were the people you surveyed? If you were a
politician or government official, how would you
act on the results of your survey
