That was in When only 1 percent of our genome codes proteins that become different parts of us — skin, hair, nails, brain, etc. This first small peak into the mystery of our DNA proves that the 99 percent is and always has been there for a reason.

As anyone can read below, he tried to mistakenly construct a scientific argument that the human genome can not sustain more than a very limited number of "genes" and argued for "the importance of doing nothing" for the rest.

Though his misnomer was doubted from the outset see the first question after his presentation calling his arguments "suspect"the misnomer lived for a generation, in spite of ample evidence that it was false. Silicon Valley startup claims to have unlocked a key to its hidden language Hal Plotkin, Special to SF Gate San Francisco Chronicle Thursday, November 21, When the human genome was first sequenced in Junethere were two pretty big surprises.

The first was that humans have only about 30, identifiable genes, not theor more many researchers were expecting. The lower -- and more humbling -- number means humans have just one-third more genes than a common species of worm.

The second stunner was how much human genetic material -- more than 90 percent -- is made up of what scientists were calling "junk DNA. The main theory at the time was that these apparently non-working sections of DNA were just evolutionary leftovers, much like our earlobes.

But if biophysicist Andras Pellionisz is correct, genetic science may be on the verge of yielding its third -- and by far biggest -- surprise. In addition to possessing an honorary doctorate in physics, Pellionisz is the holder of Ph.

In a provisional patent application filed July 31, Pellionisz claims to have unlocked a key to the hidden role junk DNA plays in growth -- and in life itself. Rather than being useless evolutionary debris, he says, the mysteriously repetitive but not identical strands of genetic material are in reality building instructions organized in a special type of pattern known as a fractal.

Another way to describe the idea: The genes we know about today, Pellionisz says, can be thought of as something similar to machines that make bricks proteins, in the case of geneswith certain junk-DNA sections providing a blueprint for the different ways those proteins are assembled.

The notion that at least certain parts of junk DNA might have a purpose appears to be picking up steam. Many scientists, for example, now refer to those areas with a far less derogatory term: Other investigators are also looking into introns from a variety of perspectives.

Other researchers have begun looking at similar questions, with most focusing on intron strands located near genes whose functions are better understood. His patent application covers all attempts to count, measure and compare the fractal properties of introns for diagnostic and therapeutic purposes.

To win a patent, Hunt notes, all an inventor must do is describe or teach some new skill that is not obvious. The provisional application lets him put the words "patent pending" on any related creations for one year, after which he must file a complete application.

In a move sure to alienate some scientists, Pellionisz has chosen the unorthodox route of making his initial disclosures online on his own Web site. He picked that strategy, he says, because it is the fastest way he can document his claims and find scientific collaborators and investors.

Most mainstream scientists usually blanch at such approaches, preferring more traditionally credible methods, such as publishing articles in peer-reviewed journals. Because of his background, the Hungarian-born brain researcher might also become one of the first people to successfully launch a new company by using the Internet to gather momentum for a novel scientific idea.

Fractals are a way that nature organizes matter. Fractal patterns can be found in anything that has a non-smooth surface unlike a billiard ballsuch as coastal seashores, the branches of a tree or the contours of a neuron a nerve cell in the brain.

Some, but not all, fractals are self-similar and stop repeating their patterns at some stage; the branches of a tree, for example, can get only so small. Because they are geometric, meaning they have a shape, fractals can be described in mathematical terms.

Although the math is much more complicated, the same is true of fractals. Decode the way that language works, he says, and in theory it could be reverse engineered. Just as knowing the radius of a circle lets one create that circle, understanding the more complicated fractal-based formula that nature uses to turn inanimate matter into a heart might -- in theory, at least -- help us learn how to grow a living heart, or simpler structures, such as disease-fighting antibodies.The stretches of DNA between genes, littered with repeating sequences, were once considered the "junk of the genome," but scientists are learning that some of this junk is far from harmless clutter.

At least three quarters of the human genome consists of non-functional, 'junk DNA', according to a new study, and the actual proportion is likely to be even greater than that.

A paper titled, “Not junk; jumping gene is critical for early embryo,” explains that what scientists assumed was a junk piece of our DNA or even a parasite regulates the very first stages of embryonic growth.

Though this was not necessarily unexpected due to previous decades of research discovering a priori assumption of total non-functionality and though some have recommended using more neutral terminology such as "noncoding DNA" instead; "junk DNA" remains a label for the portions of a genome sequence for which no In a paper.

The remaining 97 percent was given the unscientific title of "junk" because secular biologists felt that over evolutionary time the DNA had lost its function. This useless DNA was the foundation for the secular argument that the genome was not designed.
