The Human Genome Project, What Essay

What would you do if you were given the power to change your genetic
code from brown hair to blond?. Man has had this ability through natural selection
for some time without knowing it, but in the near future scientist will be
able to speed the process of natural selection by changing a persons genes.

Scientists have identified what constitutes human DNA located in the nucleus
of a cell. The Human Genome Project was established to identify the genes
that make us who we are and is now an international organization. The massive
task of identifying the numerous gene combinations has created a problem.
In the nucleus are 22 genomes, plus two sex chromosomes which have already
been identified. In the 22 genome there are approximately 3 billion base
pairs of DNA which contain 50,000 to 100,000 genes, a basic unit of heredity.

The identification of these base pairs is the goal of the Human Genome Project,
which started in 1990 and whose job it is to identify the letters or chromosomes
in DNA. These letter
s represent nulcleotides called adenine, guanine, thyamine,
and cytosine (or A, C, T, G). (’92 BSCS pg. 1)
The Human Genome Project
idea originated in the mid 1980’s and was discussed in the scientific community
and media through the latter part of that decade. In the United States the
combined effort of the Department of Energy and the National Institute of Health
were involved in the project planning. (The National Center For Genetic Reasearch)
The Human Genome Project has several goals including identifying the genes
of a human assessing the genes and comparing human DNA to that of bacteria,
yeasts, the fruit fly, mice, and the Arabidopis thaliana, a small genome plant
that grows rapidly. A major purpose is to determine how evolution proceeds
from lower organisms to humans, and discover why the smaller genomes of animals
have less junk or unneeded DNA.

Geneticists use two types of maps to characterize
the genes they discover–a genetic linkage map and a physical map. A genetic
map registers the distance between the fragments of DNA we know according to
the frequency with which they are inherited. The physical map measures the
actual physical distance between two markers. Scientists want to map and develop
technology for rapid genotyping, plus develop markers that are easy to use
as well as generate new mapping techniques. (Instrumentation) Scientists
can map genes but it is still expensive. One of the ongoing goals of the Human
Genome Project is to get the cost of mapping a gene down to 50 cents per base
pair. (’92 HSCS pg.3)
The enormous information that is and has been generated
by the project is used to link sites together around the world through the
internet and now some information can be acessed by the general public. Another
of the project goals is to create a sequencing capacity at a collective rate
of 50 Mb per year. This is supposed to result in the completion of 80 Mb by
the end of FY 1998.

Many people question whether the Human Genome Project
is worth the money spent on it and will it be used negatively toward those
who have traits that are considered undesirable by insurance companies and
other corporations? The HUMAN GENOME ORGANIZATION has a council of scientists
and doctors worldwide who meet to discuss the effects of identifying an individual’s
genes. In the 1996 Genetics Confidentiality and Nondiscrimmination Act an
attempt to addresss this issue as noted in Section 2, ” The DNA molecule contain’s
an individual’s genetic information that is uniquely private and inseparate
from one’s identity. Genetic information is being rapidly sequenced and understood.

Genetic information carries special significance. It provides information
about one’s family, and more importantly, provides information about one’s
self and and one’s self perception.”
Genetic information has been misused,
harming individuals through stigmitization and discrimination. The potential
for misuse is tremendous as genetics transcends medicine and has the potential
to penetrate many aspects of life including health and life insurance, finance,
and education. Experts advocate that genetic information should not be collected,
stored, analyzed, nor disclosed without the individual’s authorization. Current
legal protections for genetic information is, however, inadequate. Uniform
rules for collection, storage, and use of DNA samples are needed to protect
individual privacy and prevent discrimination while permitting legitimate
medical reasearch. The report further states that the reading of a minors
DNA should be only with parental or legal guardian consent and only if the
analysis benefits the individual. The need for legislation on reading genes
must be addressed prior to the final research breakthrough on this controversial
issue in order to avoid discrimination against
and protection of individuals.

Nineteen states have already enacted laws that ban genetic discrimination.

The positive uses, however, for the Human Genome Project far outweigh the
While the Genome Project has major work yet to be done much
has already been accomplished. A significant discovery is that over half
of the genes sequenced were previously unknown even though mass genetic mapping
had taken place over the last decade. The project revealed that yeast has
12 million base pairs and 6,000 genes. The yeast gene has already provided
scientists with a valuable insight into medical disorders such as cancer, neurological
problems, and skeletal disorders. The project was completed some two years
ahead of schedule because of mass automation and the fact that over a 100 laboratories
in the United States, Canada, European Union, the United Kingdom, and Japan
participated in the research. The genes were sequenced 55 % by the Europeans,
17 % by the Sanger Centre, 15 % by WUSL, 7 % Stanford Universioty, 4 % by MCGill
University in Canada, 2 % by the Institute of Physical and Chemical ReasEarch
in Japan. The start of the Yeast Genome hunt began in 1950 when Robert Mortimer
tried to
map all of the genes in the DNA of the yeast organism. Then in
the 1980’s Maynard Olson made a physical map of the genes of yeast by cloning
overlapping DNA fragments. The project spent some 30 million dollars to finish
the study.( Yeast Genome Sequenced)
The Human Genome Project is a continuing
quest and will be supported for several years until it completes the entire
gene sequence for humans and compares it to the genes of the other organisms.

The planned goals until 1998 include completing a sequence tagged site physical
of the human genome at a resolution of 100Kb. The organisms that are supposed
to be identified are a map of the mouse at a resolution of 300Kb, Escheria
Coli and Drosophilia melanogaster and bringing C. elegans to near completion
. Comparisions of mice DNA with selected portions of human DNA are areas of
high biological interest. The organiztion will continue to identify issues
and policies surrounding the ethical end of the genome debate, foster greater
acceptance of human and genetic variation, enhance and expand public knowledge
and professional education, diversify and expand the transfer of technology
both into and out of centers of genome reasearch. The price of reasearch is
increasing as more and more labs become invol
ved with the project. The projects
goals are projected to cost almost 200 million annually in comparison with
170 million for the FY 1994.

The knowledge and potential that the Human
Genome Project will produce are astronomical. Identification of inherited
diseases could be found in the fetus and then changed to both save lives and
prevent devasting diseases. The Human Genome Project is, and will, be an ongoing
project for many years to come. Today we know just one-tenth of what research
will reveal in a short few years yet we already have the knowledge to change
and alter genes. Currently, this power is limited but in the near future scientist
will have control over a factor originally associated with only natural reproduction.
