Craig Venter contributed significantly to science and humanity by inventing a synthetic cell. He accomplished this by constructing the genome of a bacterium and by incorporating it into a cell. The cell was made by joining together the genome of a pathogen from small stretches of DNA that are synthesized in the laboratory. The genome created was then inserted into an empty cytoplasm of a related bacterium. The pathogen use is called mycoplasma mycoides, it usually infect goats.The cell is the first synthetic life form in the world and it open the way for new types of research.
