Real-time monitoring of RNA splicing in living cells moves step closer with novel fluorescent probe
Numerous biological processes depend on molecules called lariat RNAs (LaRNAs). These lasso-shaped structures form in the cell during RNA splicing. During this process, transcribed RNA strands convert to messenger ...

The pre-history of life: Elegantly simple organizing principles seen in ribosomes
With few exceptions, all known forms of life on our planet rely on the same genetic code to specify the amino acid composition of proteins. Although different hypotheses abound, just how individual amino acids ...

Scientists create potent molecules aimed at treating muscular dystrophy
While RNA is an appealing drug target, small molecules that can actually affect its function have rarely been found. But now scientists from the Florida campus of The Scripps Research Institute have for the first time designed ...

Gold nanorods could improve radiation therapy of head and neck cancer
Radiation therapy is an important part of head and neck cancer therapy, but most head and neck tumors have a built-in mechanism that makes them resistant to radiation. As a result, oncologists have to deliver huge doses of ...

Study uncovers how DNA unfolds for transcription
(PhysOrg.com) -- The human genome contains some 3 billion base pairs that are tightly compacted into the nucleus of each cell. If a DNA strand were the thickness of a human hair, the entire human genome would ...

Biologists offer clearer picture of how protein machine systems tweak gene expression
Indiana University biologists have found that specific types of RNA polymerase enzymes, the molecular machines that convert DNA into RNA, can differ in function based on variation in the parts -- in this case ...

Early evolution maximized the 'spellchecking' of protein sequences
As letters of the alphabet spell out words, when amino acids are linked to one another in a particular order they "spell out" proteins. But sometimes the cell machinery for building proteins in our bodies makes a mistake ...
