Though the human genome was fully sequenced in 2001, the most promising work in genomics has just begun and not even in the study of human DNA. Human cells are outnumbered by bacterial cells by a factor of ten to one, and, as the rest of this site alludes to ad nauseam, there is strong reason to believe that bacteria are to blame for many of the chronic diseases from which humans suffer. Genetically speaking, we know relatively little about bacteria that persist in humans. The field is ripe for advances.

You may wonder how a researcher can view and understand a particular bacterial genome. On their own, they cannot. Progress in genetics is a group effort, and requires partnering with one of the handful of heavyweight institutions in the world that have developed resources allowing for genome interpretation. Several such institutions exist in the US. The NIH has bacterial protein sequencing tools at its disposal. The Broad Institute at MIT as well as the Washington University Genome Sequencing Center have also developed tools that allow for genome sequencing.

Many would argue though that the Institution most on the bleeding edge when it comes to genome sequencing technology is the J. Craig Venter Institute, formerly known as Tiger. Headed by transformative iconoclast and entrepreneur J. Craig Venter, the Institute is a non-profit research center that was founded in 2006. It has facilities in Rockville, Maryland and La Jolla, California and employs over 400 people, including Nobel laureate Hamilton Smith.

Even those of us who live under rocks have heard of the Human Genome Project, a massive international scientific research project the aim of which was to understand the genetic makeup of the human species. Its primary goal was to determine the sequence of chemical base pairs which make up DNA and to identify the approximately 25,000 genes of the human genome from both a physical and functional standpoint.

The goal of the Human Genome Project was to understand the genetic makeup of the human species.

A working draft of the genome was released in 2000 and a complete one in 2003, with further analyses yet to be completed and published. Meanwhile, a parallel project was conducted by the private company Celera Genomics. Most of the sequencing was performed in universities and research centers from the United States, Canada and Great Britain.

Most researchers would agree that the Human Genome Project was launched in order to answer the long-standing question, “Who am I?” The goal was to identify and sequence every single human gene. By doing so, many researchers were certain they would uncover causes for most of the chronic diseases that plague humankind. At the project’s start, scientists were faced with a multitude of unknown sequences to decipher and understand. Surely such sequences would offer up answers to disease, and specific genes would be found that would correlate with specific illnesses. In a Gattaca-like environment, people would then be informed early in life that they had “the gene” for MS or “the gene” for breast cancer. Scientists would work fervently to identify and change the expression of such disease-causing genes, finally developing enough gene therapies to eradicate human disease. The above scenario has an abiding appeal, largely because the idea that our genes dictate our health is so temptingly simplistic.
