#WHO MAPPED THE HUMAN GENOME CODE#

… which opens the door to all sorts of options. The point of genome research is to locate the genes and determine just how the four bases are sequenced, and then to learn what the genes actually do… Other genes have been located but their functions are unknown, and still others remain entirely elusive. Watson’s career was also punctuated by a number of offensive and scientifically erroneous comments about his beliefs on race, nationalities, homosexuality, gender. James Watson was the first NHGRI Director and appears here as part of our history collection. This timeline lists key moments from the history of the project. Today, researchers know the positions of some genes that control our medical traits. Completed in April 2003, the Human Genome Project gave us the ability to read nature's complete genetic blueprint for a human. The next step will be to determine how this battle is played out. It could lead to preventing or curing diseases, because genetics is what getting sick is all about - our genes are trying to fight off the genes of a virus or bacteria. Discovering the secrets of the sequence is still in its infancy.īetter understanding the human genome will tell us a lot about how life works. The finished sequence was completed, with 99.99-percent accuracy, in 2003. We don't have any idea about the purpose of the other 96 percent of base pairs, consequently termed junk-DNA. The human body has about 3 billion base pairs, but only about 4 percent of those pairs constitute DNA that affects gene function. The sides of the ladder are made of sugar and phosphate molecules. In a DNA molecule, which is shaped like a twisted ladder, the bases are the chemicals that interlock to form the rungs of the ladder. Each of these genes is composed of a unique sequence of pairs, each with four bases, called base pairs.

According to the Human Genome Project, there are between 26,000 and 40,000 genes in the human body. Researchers mapped 92 percent of a sample human genome, representing nearly 3 billion base pairs. A nucleotide is the basic unit of nucleic acid, which is found in the 23 pairs of chromosomes in the human body. The Human Genome Project, which announced its final release in 2003, was certainly a solid start in surveying our hereditary instructions and well over half finished. What researchers are trying to do is construct a detailed genetic map of the human genome and determine the entire nucleotide sequence of human deoxyribonucleic acid ( DNA). In June 2000, scientists from the Human Genome Project and from Celera Genomics both announced that they had assembled a working draft sequence of the human genome, a major step in cracking the code.

Once the code is broken, it will reveal many secrets of how the human body works, and it could lead to greater disease prevention. If you think of the human body as big, complicated, encrypted code, then the scientists mapping the human genome are attempting to break that code. Photo courtesy DOE Joint Genome Institute
