John Craig Venter is a highly influential American scientist specializing in genomics. Genomics is the study of genomes, which are the complete sets of genetic instructions found in an organism. Venter is best known for leading one of the first draft sequences of the human genome. He also led the first team to successfully transfect a cell with a synthetic chromosome. His work has transformed how we understand the building blocks of life. Because of his contributions, he has appeared on Time magazine's list of the most influential people in the world.

A major part of Venter's success involves a technique called whole genome shotgun sequencing. In this process, a long strand of DNA is broken into many small, overlapping fragments. These fragments are sequenced individually at high speeds. Then, powerful computers find the overlapping parts to reassemble the entire sequence. While the public Human Genome Project initially rejected this method, Venter believed it was the fastest way to gather data. His Celera Genomics company used this method to compete with the public project. This competition helped the human genome be mapped three years earlier than expected. In 2000, Venter and Francis Collins announced the mapping alongside President Bill Clinton and Prime Minister Tony Blair.

Venter has founded several organizations to advance different areas of biological research. He founded Celera Genomics to pursue private-sector genomic data. He also established the Institute for Genomic Research (TIGR) and the J. Craig Venter Institute (JCVI). The JCVI is a nonprofit organization that conducts research in synthetic biology. Synthetic biology involves redesigning organisms for useful purposes. The institute has facilities in La Jolla and Rockville, Maryland.

In 2005, he co-founded Synthetic Genomics to research using modified microorganisms for clean fuels. This company later entered a $600 million collaboration with ExxonMobil to develop biofuels.

His career has also focused on exploring the genetic diversity of our oceans. In 2004, Venter announced the Global Ocean Sampling Expedition. This project aimed to assess the genetic diversity in marine microbial communities. He used his personal yacht, the Sorcerer II, to travel around the world for this mission. The expedition began as a pilot project in the Sargasso Sea in August 2003. It eventually circumnavigated the globe and returned to the United States in January 2006. This work helps scientists understand the role of tiny marine organisms in nature's fundamental processes.

Venter has made significant breakthroughs in the field of synthetic life. In May 2010, his team became the first to create what was described as "synthetic life." They achieved this by synthesizing a very long DNA molecule that contained an entire bacterium genome. They then introduced this DNA into another cell to start the life process. In 2016, he reported the creation of Syn 3.0. This is a synthetic genome that contains only 473 genes. This is the fewest genes of any freely living organism. Scientists hope these stripped-down cells will be valuable tools for future research.

Beyond creating life, Venter has also studied the genome of individual humans. In 2007, a team led by Sam Levy published the DNA sequence of Venter himself. This project used microfluidic Sanger sequencing to identify millions of DNA variations. These variations include single-nucleotide polymorphisms, which are changes in a single DNA building block. They also include larger changes like insertions, deletions, and inversions. This data is available through the Human Reference Genome Browser. This tool allows scientists to navigate and compare different human genetic sequences.

Venter's early life and personal history shaped his scientific drive. He was born in 1946 in Salt Lake City, Utah. During his youth, he was not a highly engaged student and preferred spending time on boats or surfing. He later served in the United States Navy as a hospital corpsman in Vietnam from 1967 to 1968. Working in an intensive-care ward influenced his desire to study medicine. He eventually moved into biomedical research, earning a PhD from the University of California, San Diego, in 1975. His experiences instilled in him a deep focus on meaningful work and the study of life.
