Human Genome Mapped, but DNA Still a Mystery

Genes more complex than scientists thought

(Newser) – A new map of human DNA shows just how complex we really are – so much so that scientists can’t even pin down which genes are making our eyes blue. "I found out that I have [only] a high probability of having blue eyes," says azure-eyed biologist Craig Venter, whose genetic code is published in a new study. "We all thought that would be simple."

Researchers spotted 4.1 million places where Venter’s DNA differed from the human genome mapped in 2001, Reuters reports. Whatever the results, Venter says he hopes they help people overcome their fears of genetic sequencing. “"Knowing something doesn't change what's in our genetic code. But knowing things maybe gives us a chance to change what could be part of our genetic destiny.”

Don't Let Scientists Patent Synthetic Life

Genome pioneer argues for open access

(NEWSER) - Craig Venter's creation of the first synthetic life form is a milestone discovery but patenting it will hold back science, argues a British scientist who helped sequence the human genome. John Sulston—who clashed with Venter a decade ago when he sought to restrict access to genome information—tells the BBC that allowing Venter to patent the organism will be "extremely damaging" because it will give his firm a stranglehold over a whole range of genetic engineering techniques.

Millionaire Pays Firm to Map His Genetic Code

Personal genome readouts now on shopping list for super-rich

(NEWSER) - A Switzerland-based millionaire is paying to have his personal genetic code mapped out, the New York Times reports. He is only the second person to ever have done so, but genetics companies say interest is high despite the $350,000 price tag for decoding all 6 billion units in an individual's genome. "I’d rather spend my money on my genome than on a Bentley or an airplane," said the retired biotech entrepreneur. More»

Scientists Move Closer to Synthetic Life

In a first, researchers create entire genome of a bacterium

(NEWSER) - Scientists have assembled the entire genome of a bacterium from basic chemicals, an important step toward creating a fully artificial organism, Reuters reports. "This entire process started with four bottles of chemicals," says Craig Venter, founder of the institute that did the work. Scientists had previously manufactured the genome for a virus, but this is the first for a bacterium, which are far more complex, notes the New York Times. More»

For Just $1K, You'll Soon Be Able to Map Your Genes

Genomics company unveiling new machine today

(NEWSER) - Want to map your genes, but don't have the $3,000 the cheapest sequencing currently costs? By the end of the year, you could be in luck: California genomics company Life Technologies Corp. will introduce a machine today that, by year's end, is expected to be able to map your entire genome for $1,000. Even better: The company says it will deliver results in one day, compared to the one week it currently takes, the Wall Street Journal reports. More»
