Little green prescriptivists

Today's SMBC starts with this panel: And ends with this one: The aftercomic: My preferred imaginary event proving evolution false would be the discovery that highly-conserved junk DNA encodes versions of the Book of Genesis in Hebrew. Much more interesting than sauropods with nylon stretchpants — especially the variorum edition.

The dark side of 'junk' DNA

Certain short, repetitive sequences of DNA, or “junk,” play an important role in the development of Ewing sarcoma, new research indicates.

The dark side of 'junk' DNA

(UNC Lineberger Comprehensive Cancer Center) Researchers at the University of North Carolina Lineberger Comprehensive Cancer Center report in the journal Cell Reports that certain short, repetitive sequences of DNA, or 'junk,' play an important role in the development of Ewing sarcoma, a rare bone and soft tissue cancer that occurs most commonly in children and adolescents.

The Dark Side of 'Junk' DNA

Researchers at the University of North Carolina Lineberger Comprehensive Cancer Center report in the journal Cell Reports that certain short, repetitive sequences of DNA, or "junk," play an important role in the development of Ewing sarcoma.

For normal heart function, look beyond the genes

Researchers have shown that when parts of a genome known as enhancers are missing, the heart works abnormally, a finding that bolsters the importance of DNA segments once considered "junk" because they do not code for specific prote...

Linking RNA structure and function

Several years ago, biologists discovered a new type of genetic material known as long noncoding RNA. This RNA does not code for proteins and is copied from sections of the genome once believed to be "junk DNA."

Variation in 'junk' DNA leads to trouble

Although genetic variants are scattered throughout the human genome, scientists have largely ignored the stretches of repetitive genetic code known as 'junk' DNA in their search for differences that influence human health and disease. Show More Summary

Reading between the genes

For a long time dismissed as 'junk DNA,' we now know that also the regions between the genes fulfill vital functions. Scientists have now developed a method to find regulatory DNA regions which are active and controlling genes.

Shedding light on the 'dark matter' of the genome

What used to be dismissed by many as 'junk DNA' is back with a vengeance as growing data points to the importance of non-coding RNAs (ncRNAs) -- genome's messages that do not code for proteins -- in development and disease. Researchers have developed a method that enables scientists to explore in depth what ncRNAs do in human cells.

Key gene in development of celiac disease has been found in 'junk' DNA

40% of the population carry the main risk factor for celiac disease but only 1% develop the disease. A newly found gene that influences its development has been found in what until recently has been known as ‘junkDNA. Celiac disease...Show More Summary

A key gene in the development of celiac disease has been found in 'junk' DNA

Coeliac disease is a chronic, immunological disease that is manifested as intolerance to gluten proteins present in wheat, rye and barley. This intolerance leads to an inflammatory reaction in the small intestine that hampers the absorption of nutrients. The only treatment is a strict, life-long, gluten-free diet. read more

'Junk' DNA plays role in preventing breast cancer

Supposed 'junk' DNA, found in between genes, plays a role in suppressing cancer, according to new research. The human genome contains around three meters of DNA, of which only about two per cent contains genes that code for proteins. Since the sequencing of the complete human genome in 2000, scientists have puzzled over the role of the remaining 98 per cent.

'Junk' DNA plays role in preventing breast cancer

Supposed "junk" DNA, found in between genes, plays a role in suppressing cancer, according to new research by Universities of Bath and Cambridge. The human genome contains around three metres of DNA, of which only about two per cent contains genes that code for proteins. Show More Summary

Matter: Telling Jewels From Junk in DNA

Some cellular DNA yields molecules that serve mysterious but important functions in the cell, new research suggests.

Not 'junk' anymore: Obscure DNA has key role in stroke damage

MADISON, Wis. -- A study of rats released today shows that blocking a type of RNA produced by what used to be called "junk DNA" can prevent a significant portion of the neural destruction that follows a stroke. The research points toward...Show More Summary

Junk DNA: How much of our genetic material pulls its weight?

Science can’t decide if our genes have more or less value than the Baldwin brothers The post Junk DNA: How much of our genetic material pulls its weight? appeared first on Macleans.ca.

Junk DNA must be…fractal ballast!

2 years agoAcademics : Pharyngula

I’ve now read two novel attempts to explain the existence of junk DNA. To a lot of people, the very idea of junk DNA is offensive: whatever process built us, whether divine fiat or the razor-sharp honing of natural selection, must be powerful, omnipotent or nearly so, and incapable of tolerating any noise or sloppiness,…

Three reasons why nobody should be surprised by junk DNA

Science writer Carl Zimmer just wrote an article in the New York Times about the junk DNA wars and it's worth a read. Zimmer presents conflicting expert opinions about the definition of 'junk' and the exact role that junk DNA plays in various genetic processes. Show More Summary

The Junk DNA Fight

From yesterday's New York Times Magazine, here's an excellent intro by Carl Zimmer to the Junk DNA Wars. In January, Francis Collins, the director of the National Institutes of Health, made a comment that revealed just how far the consensus has moved. Show More Summary

Man Unable Or Possibly Just Unwilling To Justify Majority Of Self

“Over millions of years, essential genes haven’t changed very much, while junk DNA has picked up many harmless mutations. Scientists at the University of Oxford have measured evolutionary change over the past 100 million years at every spot in the human genome. ‘I can today say, hand on my heart, that 8 percent, plus or […]
