Scientists discover second DNA code

The breakthrough was made as part of a project funded by the US National Human Genome Research Institute.
It has long been believed that DNA is responsible for telling the cells how to make proteins, but thanks to an international collaboration of research groups scientists now believe they have identified a second DNA code, one that instructs cells on how genes are controlled.

"For over 40 years we have assumed that DNA changes affecting the genetic code solely impact how proteins are made," said John Stamatoyannopoulos who is lead author of the study. "Now we know that this basic assumption about reading the human genome missed half of the picture."

The find is important because it implies that changes in DNA that occur due to illness or age may be having more of an effect that previously believed.

"Many DNA changes that appear to alter protein sequences may actually cause disease by disrupting gene control programs or even both mechanisms simultaneously," said Prof Stamatoyannopoulos.

Dang , there we go an article for all of you attributing too much credibility to science. Imagine that this fact is only being discovered now. Wondering how much time they will still need until discovering God's secret ingredients within our bodies. Probably never! The wonders of science are moving with Snail steps. Last I checked, modern science has lead to low infant death rates, travel to the moon and peering into the deep cosmos and into the origins of our planet and the human species. Not to mention the science that went into developing the computer and internet and electricity you are us... [More]

The discovery showed how frugal nature sometimes is, using the same code for two different purposes. The idea is to pack as much info into as small a space as possible I guess. I'm kinda curious what "God's secret ingredients" might look like and what function they might serve. Maybe genetic code for the soul? I'm sorry but that sort of statement is very hard to refrain from ridiculing.

Last I checked, modern science has lead to low infant death rates, travel to the moon and peering into the deep cosmos and into the origins of our planet and the human species. Not to mention the science that went into developing the computer and internet and electricity you are using. Most of which has developed over the last hundred years. Edit: And don't require any particular religious belief to accept, save extreme fanaticism. And at cost i might ask ? In the same time to what good? Convenience?

And at cost i might ask ? Mostly time and effort and money. The medical do require testing. The proudest moments have been when those subjects were volunteers, the darkest were when they were forced. In the same time to what good? Convenience? Yes. The conveniences of parents being able to watch their children grow to be adults. The internet has facilitated communication across nations and encouraging the free exchange of ideas, something that leads to general improvement and progress for the societies that partake in it, something we can see throughout history, take the Library in Alexandria ...

Scientists have long believed that DNA tells the cells how to make proteins. But the discovery of a new, second DNA code Thursday suggests the body speaks two different languages. The findings in the journal Science may have big implications for how medical experts use the genomes of patients to interpret and diagnose diseases, researchers said. http://uk.news.yahoo...67.html#3EPwQy2 Have you noticed that there is no explanation on what was discovered? Nothing scientific in this article. When I searched for it, I couldn't find out just what that code was and how they found it. It is all so vag... [More]

But WHAT is interesting? What it is? I need to know more. The second DNA code is interesting.

The second DNA code is interesting. Yes, but what is it? I am still looking. "John Stamatoyannopoulos" what a name! This is a better explanation: " The genetic code is similar for all organisms and is stored in one of the two DNA strands as non-overlapping, linear sequence of nitrogenous bases Adenine (A), Guanine (G), Cytosine and Thymine (T). These four letters are the 'alphabet' of the genetic code and are used to write code words. The code consists of three-letter words (also called triplets or codons). There are a total of 64 codons. Now, researchers have found that the codons, which th... [More]
