2007 Pathways and Access to Careers in Technology
Field Team Research Group 7E: Genetic Engineering
Our Group Members
include: Laura Flynn, James
Tillman, Jacob Wyte,
and
Warren Gates.
Our PACT Challenge:
To learn how biotechnology works in all areas
of life.
Also to learn how to extract and process DNA.
The facts we
learned about DNA Extraction: There are 200,000
combinations
of DNA. The electric currents causes the DNA to move
from the negatively charged side to the positively
charged side. You
don't want contamination in the gels
when extracting DNA, because
results are crucial.
The facts we
learned about genetic alterations: You can make food
that isn\'t affected by bugs. You can put medicine
in the foods you
eat insterad of actually getting the
shot to be healthy. (For example
bananas, and anti-freeze
strawberries).
The facts we
learned about bioengineering: The study of tools from
living things. You are able to alter different organisms.
It can help
cut down on the use of different pesticides.
We learned how to extract DNA and highlight
identifying
characteristics of individuals utilizing
groundbreaking
biotechnology to solve the challenge. To
successfully
identify the culprit we had to: We put DNA into wells.
Then once
all of them were filled we put carbon strips
on each side. Next we
used 50 watts of electricity. Finally
we stained it and study who
was the culprit.
Based on these studies and our suspect identification
techniques our recommendation to the crime
lab of Stemville, KY is: Genetic Engineering Genetic engineering
is
not merely producing a twin or multiple twins of an
individual, but
actually changing the genetic makeup of
a person. The steps
themselves seem quite simple but its
harder than it looks. There
are four steps in this process.
A portion of the donor\'s DNA carrying
the right gene is
snipped out using restriction enzymes. A special
ring of
DNA is spliced into the plasmid, which is sealed up with
DNA
ligase and introduced into bacteria. The bacteria then
reproduces.
An important factor of genetic engineering
is that if someone can't
fight off diseases than they
can replace the genes with better ones.
The negative side
to this is if you take the genes from someone who
is likely
to have cancer, the person you put those genes into now
have
that same chance of getting cancer or any other desease
that person
was prone to getting. There are many examples
of genetic engineering
some of them include: taking the
genes from a fish resistant to freezing
and putting them
into strawberries. Another example is Dolly the sheep
(the
first mammal to ever be cloned sucessfully). GMO's (Genetically
Modified Organisms) are very closely related to genetic
engineering.
The only difference is that GMO transfers
DNA when genetic
engineering transfers specific genes.
Therefore genetic engineering
will be very important in
the future. |
