Stem Cells and DNA Fingerprinting

Catalyst:
What
is the complementary strand of DNA
to ACTTGCTACG?
We’ve talked a lot about genetically
engineering human beings. Do you think it is
morally acceptable to genetically engineer
non-human life forms? (Plants, non-human
animals, etc.). Explain why or why not.
Introduction

As we have learned over the last few
days, humans can genetically engineer
organisms
Directly

alter genes and cells
We haven’t yet reached the point of
Gattaca—but we’re getting there…
Transgenic Organisms

Transgenic organism: an organism that has
DNA from another species put inside of it
by scientists
 Trans-:
across
 -Genic: gene

Key Point #1:
 Scientists
use restriction enzymes to create
transgenic organisms
Restriction Enzymes

Restriction enzymes cut out the gene from one
organism, so it can be placed into another

Adult Stem Cells
In Louisiana, it is ILLEGAL to
create embryonic stem cells
 So all local research is done using
adult stem cells

While You Are Waiting…

Write a letter to the editor of the New
Orleans Times-Picayune
Identify
applications of stem cell research
Explain your position on stem cell research
Is
embryonic stem cell research morally
acceptable?
Is adult stem cell research morally
acceptable?
Why or why not?
Exit Question
Next week, we will study
cloning.

Please
tell me everything you
already know about cloning.
Please tell me everything you
don’t know but want to find out
about cloning.
