Craig Ventor first first self-replicating, synthetic bacterial cell
ROCKVILLE, MD and San Diego, CA (May 20, 2010)— Researchers at the J. Craig Venter Institute (JCVI), a not-for-profit genomic research organization, published results today describing the successful construction of the first self-replicating, synthetic bacterial cell. The team synthesized the 1.08 million base pair chromosome of a modified Mycoplasma mycoides genome. The synthetic cell is called Mycoplasma mycoides JCVI-syn1.0 and is the proof of principle that genomes can be designed in the computer, chemically made in the laboratory and transplanted into a recipient cell to produce a new self-replicating cell controlled only by the synthetic genome.

genitalium genome, they designed and inserted into the genome what they called watermarks. These are specifically designed segments of DNA that use the “alphabet” of genes and proteins that enable the researcher to spell out words and phrases. The watermarks are an essential means to prove that the genome is synthetic and not native, and to identify the laboratory of origin. Encoded in the watermarks is a new DNA code for writing words, sentences and numbers. In addition to the new code there is a web address to send emails to if you can successfully decode the new code, the names of 46 authors and other key contributors and three quotations: "TO LIVE, TO ERR, TO FALL, TO TRIUMPH, TO RECREATE LIFE OUT OF LIFE." - JAMES JOYCE; "SEE THINGS NOT AS THEY ARE, BUT AS THEY MIGHT BE.”-A quote from the book, “American Prometheus”; "WHAT I CANNOT BUILD, I CANNOT UNDERSTAND." - RICHARD FEYNMAN.
The JCVI scientists envision that the knowledge gained by constructing this first self-replicating synthetic cell, coupled with decreasing costs for DNA synthesis, will give rise to wider use of this powerful technology. This will undoubtedly lead to the development of many important applications and products including biofuels, vaccines, pharmaceuticals, clean water and food products. The group continues to drive and support ethical
Synthetic biology can be a somewhat controversial topic, some argue that it is “going against nature” and some argue that it helps us discover and create new things. It is important to consider what life actually is, the pros and cons of synthetic biology, and the morals behind it.
The author explains the basics of DNA by describing the simple part of it, “proteins are the molecules that do all of the work in every organism, from carrying oxygen, to building tissue, to copying DNA for the next generation” (Carroll 73). He also explained the four bases that are building blocks that are held together by strong bonds and are represented by the letters A, C, G and T. Scientist also learned that A and T always pair with each other as well as G and C, this helps them because if they know one strand of DNA they already know the second because of how the bases match up. The author states that scientists have found about 500 genes that exist in all forms of life, the author explains that these genes are “immortal”. These genes have endured millions of years of evolution and have not been mutated because they are essential for every organism to have; these genes can have important jobs such as decoding of the DNA and RNA and making
Along with this, he volunteers at a local hospital in the city, helping to improve the Calgary community. Science and biology have been an integral part of his entire life and have served as a source of inspiration. Over this past year, iGEM has provided him with the chance to further explore the field of synthetic biology along with connecting him with like minded people and peers.
cells also have the potential to cure a myriad of diseases, including Alzheimer’s disease, Parkinson’s disease, diabetes, and many others. The cells of the four day old human embryo can be programmed to become virtually any cell in the body making them a very valuable commodity. All this sounds very promising until one realizes the cost of
The DNA Mystique looks into the power of the gene in today’s society. Dorothy Nelkin and Susan Lindee (1995) describe the evolution of the gene as a cultural icon. Society puts a huge emphasis on understanding everyday behavior and the “secret of life” through genetic essentialism. According to Nelkin and Lindee genetic essentialism “reduces the self to a molecular entity, equating human beings, in all their social, historical, and moral complexity, with their genes” (p. 337). DNA is used as a way to define the individual’s true self and understand the evolution of a person’s identity. Nelkin and Lindee discuss the intersection of science and popular culture to shape the cultural meaning of the gene (p. 338). They lay out a timeline of genetic mapping and the use of genome research to determine future outcomes.
In the Biotech Century scientist are now able to splice, recombine, insert, and stitch living material into economic utilities. Viruses and genes are isolated, and placed
The article starts “The human genome is three billion letters long. About 240 million letters of it, scientists estimate, is viral. Yes, eight percent of human DNA comes from ancient viruses that once infected our ancestors.” These two statements instantly captures the audience attention and draws them into wanting to know where exactly the author is heading.
point mutation, frameshift, etc.). The advantage of using a synthetic system like ours is that the entire system is located on a plasmid and we hypothesise that the majority of mutations resulting in resistance will occur in the plasmid sequence. Unlike natural systems that contain many factors with genes encoded throughout the genome, our synthetic system allows us to monitor mutations in a more tractable manner. Further studies of the constant evolution of microecologies using this or other synthetic systems may allow researchers to tune in on “evolutionary steps” in a more accountable manner.
and that is dealing with the DNA sequence. They say the human genome is a set of instructions
Sanger and his colleges designed, synthesized and assembled a 1.08 mega base pair Mycoplasma Mycoses JCVI-syn1.0 genome. The design of the genome was based on two laboratory strains of M.mycoides. There were 19 polymorphic differences between the synthetic genome and the natural genome. They marked the synthetic genome with four watermark sequences to replace one or more cassettes in regions experimentally demonstrated or predicted to not interfere with cell viability.
“A potential key to the secret of life was impossible to push out of my mind” (Watson 35). Without Crick and Watson’s development on the anatomy of DNA, the foundation for modern day knowledge on genetics and inheritance would have never existed. Francis Crick and James Watson were two scientists who discovered and deciphered the structure and different parts of DNA. Subsequently, if they never conceived the whole idea of a human genome, the entire maintenance of life’s code would remain a mystery. Throughout the race where the men were aiming to be the first ones to unscramble the DNA code, Crick and Francis encountered and exchanged ideas and hypotheses with other scientists in order to produce the structure and function of the DNA
The computer is one of the greatest gifts from science. If we check history, “computer” was just a name of a job title. That name has transferred to a machine as we see computers in this generation. Then, Scientists have invented biocomputers with systems included to build out of genes, proteins, cells and O.R. operations. Biocomputers have become so advanced over the past few years. In 2000, first big innovations came to Boston University by James Collins and his colleagues. They have stitched together inhering genes to make a genetic switch. Also, synthetic biologists performed all basics Boolean operations of digital logic by creating genetic parts. In 2011, researchers programmed cells to communicate with each other through chemicals. Synthetic Biologists aimed to see the abilities of cells to run some programmes that they designed by biocomputers.
Synthetic biology is still considered an emerging science. Most, if not all, of its available tools remain in the controlled lab environment. For the sake of discussion, synthetic biologists and conservationists hypothesize how the tools could be implemented in the field in beneficial
Thirteen years have passed since the human genome has been decoded. From then on, we knew exactly what makes us human: a string of code telling our cells what to do. Unsurprisingly, the public’s imagination had never been so zealous in discerning what a single biological discovery meant for the future of humanity. Thirteen years ago, news sources buzzed with hot-topic articles warning us of designer babies and man-made crops. Based on the frantic journalistic climate of the time, one might think us normal people would soon be replaced by post-humans. To find crude evidence for the decade’s excitement (or disdain) for the upcoming human genetics revolution, one needs only check google search trends for words like ‘genetic enhancement’ or ‘designer baby.’ Interest peaks around 2003, the year of the human genome project’s conclusion (figure 1). Today, many are not interested in current genetic events. Despite the public’s dwindling interest in the human genome, the scientific community a been working along with increasing fervor.
