Figuring out genes - the biological units that
determine the characteristics and capabilities of all
terrestrial life - is ostensibly in the interest of
helping humanity. The theory goes that if we can find out
how the body works - including what causes it to die,
become diseased, and fail in other ways - we can improve
on what nature has forced upon us.
Human genetics research positively impacts our lives.

children from Choose
Better Human Genes.
The ability to test for genetic disposition to
Alzheimer's and breast cancer gives at-risk individuals
the option of preparing for or attempting to prevent the
disorders, as discussed at Reuterlink
Extra: Genetic Testing.
Genetic research on animals, with which humans share many
genes, is on its way to curing hemophilia, Down's
syndrome, herpes, and arthritis. And genetherapy, the
altering of genetic material in living humans, is being
tested to combat cystic fibrosis, some cancers, and AIDS,
as detailed at the National
Cancer Institute Fact Sheet.
The conceivable potential for genetics research to help
humanity is mind-boggling. No more cancer or birth
defects. No more dieting to stave off obesity. No more
brushing daily to avoid cavities. No more planning for
death in your 70's. In fact, every disease caused by
faulty or missing genes is a candidate for cure by
genetic research. See What Can DNA
Research Do?
Given its potential for good, who would object to
genetics research? A lot of people, as it turns out. If
knowledge is power, pushing the boundaries of altering
humans at the genetic level has the power to harm
humanity.
Some people - many in accordance with religious beliefs -
object to any altering of human genes. If you change the
structure of what God created, they say, aren't you
pretending to be God? A fascinating genetics dialogue
between religious and scientific experts is transcripted
by Online
NewsHour at Cloning Mammals.
The Science
Religion and Technology Project of the Church of Scotland
offers a broader analysis of genetics, ethics, and
religion.
Even if you admit that genetic research is mostly
beneficial, you probably draw the line somewhere
regarding what's acceptable. When Dolly the sheep was
cloned in 1997, for example, you - like many people -
might have felt an intuitive alarm. If it's cloning sheep
today, after all, cloning humans can't be far off. Read Britain
Prepares to Legalize Embryo Cloning, and Cow-Human
Clones.
Potentially more disturbing is the possibility of cloning
headless humans for the purpose of growing internal
organs, as discussed at British
Scientist Create Headless Frog Embryo.
The ability to grow human embryos, livers, and (perhaps)
brains in animals isn't fiction, however, as outlined at Body
Shop Sells Body Parts. Neither is eugenics, the
attempt to create a "better" human at the
genetic level, as detailed at Pragmatism
and Genetic Engineering. The debate rages on about
what is "faulty" (Deafness? Baldness? Albinism?
PMS?) and what is a variance that contributes to the
strange and wonderful diversity of humanity.
Finally, the sidelines of genetic research can be as
disturbing as its advances. For example, most genetics
research is corporate, which raises ethical and legal
questions about who owns genes and the tissue that
contains them. Glaxo, Columbia University, and the US
National Institutes of Health have applied for (and been
granted) patents to your genes, as detailed at Examples of
Patented Human Genes.
In fact, whole populations have been patented because of
their abilities to resist common conditions, such as
baldness, HIV, and asthma, as seen at Hunting for
Human DNA.
Few sciences prompt such strong feelings of soaring
optimism, gloomy foreboding, or just plain creepiness as
genetics. Because of this, ethics is as much a part of
genetic research as genes are a part of DNA, and you
don't have to understand the science of genetics to be
interested in its ramifications. It's a brave new world!
Practically every breakthrough in genetic research sparks
a debate about its ethical limitations. Arm yourself with
both questions and answers at these sites.
DNA
Learning Centre
This amazing site introduces you to the magic of DNA,
the cellular matter that contains genes. Start with DNA
from the beginning, a walk-through of key concepts in the
entire range of genetics - from basic inheritance to
cutting-edge DNA analyses (Netscape Communicator or
Microsoft Internet Explorer 4.0 or later and RealAudio
and Shockwave plug-ins are required). Register (it's
free) and load the tutorial, which explains the primer's
interactive features, or skip directly to the primer
itself. Other parts of the site include feature articles,
animations, and exercises (under Research); publications,
texts, and lab kits for sales (under Products); and
explanations and brochures for workshops and field trips
(under Programs). Links leads to other online resources,
and Gene Talk houses chat groups and forums.
Human
Genome Project Information (HGP)
The world's best-known effort to catalog the 80,000 genes
as well as the 3 million chemical bases that make up
human DNA is the focus of this site. Much of the
information is palatable only the geneticists, but there
is also plenty for the casual observer. Human Genome News
is a monthly, archived, and searchable newsletter with
articles on the project; links to genetics news online;
and analysis of ethical, legal, and social implications
of HGP. The About section covers HGP progress, history,
and goals. Basic information includes a glossary, a
genetics primer, and a FAQ. If you bookmark only one
source of genetics information, this should be it.
The DNA Files
Based on the National Public Radio series by the same
name, this entertaining and informative site offers
excerpts of eight radio programs on topics ranging from
the Human Genome Project (the previously reviewed HGP
site) to DNA & Behavior to Predictive Genetic
Testing. RealAudio files and summaries are located under
About the Programs. Interact proposes realistic scenarios
involving Marfan Syndrome, breast cancer, and transgenics
(blending genetic material of different animals), then
asks you to make choices based on the information. See
how your choices compare with other readers'. Genetics
Resources lists on- and offline sources of information
about the topics in each program.
New
Scientist Planet Science: Cloning: A Special Project
Warning: Vivid imagery ahead! More than 30 news articles,
FAQ, and editorials on this site might lead you to
picture a pasture with 100 identical cows, a lab with 10
headless humans, or a room with your great grandmother
"reborn" through cloned cells. With engaging
text and colorful illustrations, this site walks you
through the science, future, and ethics of cloning.
Ultimately raising more questions than it answers, it is
nevertheless a fairly unbiased and thorough overview of
the most captivating arm of genetics. Make sure to scroll
down the Web Links section, which lists further online
resources.
The Natural History
of Genes
This site pays more than lip service to genetics through
many fascinating activities and experiments. Go to Core
Genetics Activities to learn how to extract DNA using
kitchen utensils, build a 3-D animal cell molecule, use
DNA evidence to solve crimes, find out your blood type,
and much more. Teens Fun Stuff and Tomorrow's Textbook
contain selections from these projects, as well as
additional experiments. Newspaper articles on genetics
from the Salt Lake Tribune are under What's in the News.
Use Find It Fast to look for specific activities and
articles on the site.
