Another one of its goals was to analyze and map the 25,000 genes in the body. The project was completed ahead of schedule. The only thing that remains now is to analyze the data. This however, can take years to finish.
The goals of the Human Genome Project can be divided into various categories. They are given below. The benefits from the project run the gamut from medicine to forensics.
