Determination of the entire DNA sequence contained in the human genome will not answer the question:
What is a human?
Geneticists will not be able to look at a person’s DNA sequence and predict everything about the appearance and characteristics of that person. Even if geneticists can identify segments of DNA as genes, the vast majority of the genes they discover still will have unknown functions.
In addition, many human traits such as body stature and intelligence result from multiple genes, and the exact number of genes that might contribute to such a trait is not obvious, nor are the ways in which those genes interact.
An individual’s genetic make-up greatly contributes to the type of person he or she is, but environmental variables such as diet, education, climate, family values, and access to health care also play a considerable role in determining an individual’s characteristics.
Before I go any further I have to declare that this subject is away beyond me, so if there is any one who has gone to the trouble of reading this far please feel free to contribute. All I can say if we do recreate ourselves I hope we do a better job than the first time around.
The increased understanding of the human genome is driven largely by rapid advances in technology. And the single most profound advance has been in the cost and the speed of sequencing.
The chromosomes of a sperm or egg contain about 3 billion base pairs, so a body cell has 6 billion. The whole set of base pairs in a gamete is the genome.
I don’t think it is possible to know all of the future effects of the human genome project, because people are coming up with new ways to use the information all the time.
Of course, the farther we peer into the future, the cloudier is our vision.
And it has a Scary side.
You will have read recently that scientists in China are editing the genetic code in human embryos.
So What wrong with that?
Is this unethical and will it be used to further the goals of those who wish to become ‘ creators’ in their own eyes.
Science has struggled to understand the mysteries of “less-than-human” beings since the late 1400s when the Spanish Inquisition first formalized state persecution of Jews and Muslims. And while the horrors of Nazi Germany exposed fatal flaws in science’s quest to build the master race, the ethical dilemmas posed by the science of eugenics are far from behind us.
While I understand that there are or will be many benefits to man from genetic engineering this is another step to manipulation for enhancing.
So are we on the threshold of modifying our own germ line and take control of our genetic destiny.?
The genetic engineering of humans — tools more powerful than a Nazi’s wildest dreams is unlocking life’s code.
The prospect of creating heritable modified genes and manufacturing designer babies that are more intelligent and beautiful than their peers is unthinkable for some.
But you would be naive to think that is wont happen . The potential for profit, in terms of both cash and the welfare of humanity, is almost limitless.
Understanding the genome will undoubtedly be the most important achievement of the 21st century, and perhaps of all time.
People looking back 50 years from now will consider medicine a barbaric, random process. If the promise of genomics is fulfilled, it will transform the lives of everyone.
It will spark many complex questions both ethical and not.
Human societies are not inferior or superior to one another but they could become so in not the so distant future.
The sequence of the human genome will underpin bio medical research for decades:
Genetic testing is not only a medical procedure. It is also a way of creating social categories that will be discriminated against based on their genetics, never mind race or religion. Genetic discrimination” will be on our heads.
Is sequencing the human genome an intellectually appropriate project for biologists?”
How close actually are we to personalized medicine?
When will we begin to see the benefits of the Human Genome Project?
To Date the genomic mapping of humans can even be used to track the migration of humans from Africa over 50,000 years ago, as well as unlock the evolutionary timeline of the origin of man.
Genomics will be used to create better crops, better meat, more sophisticated robotics, new materials, and even whole new forms of life.
However in man the things which are not measurable are more important than those which are measurable.
Because of the ethical issues that it raises and the potential that it has to change human reproduction, and ultimately human society, it is crucial that we start to establish the boundaries of this science before the technology advances even farther.
On the other hand.
If man is to colonize the vastness of the Universe he will have to be recreated.
