Lariats: How RNA splicing decisions are made

Lariats are discarded byproducts of RNA splicing, the process by which genetic instructions for making proteins are assembled. A new study has found hundreds more lariats than ever before, yielding new information about how ...

Locked down, RNA editing yields odd fly behavior

Because a function of RNA is to be translated as the genetic instructions for the protein-making machinery of cells, RNA editing is the body's way of fine-tuning the proteins it produces, allowing us to adapt. The enzyme ...

Mice with fewer insulin-signaling receptors don't live longer

Scientists studying longevity thought it might be good to lack a copy of a gene, called IGF1 receptor, that is important in insulin signaling. Previous studies showed invertebrates that lacked the copy lived longer, even ...

Biologists uncover a novel cellular proofreading mechanism

(PhysOrg.com) -- To make proteins, cells assemble long chains of amino acids, based on genetic instructions from DNA. That construction takes place in a tiny cellular structure called a ribosome, to which amino acids are ...

New thinking on regulation of sex chromosomes in fruit flies

Fruit flies have been indispensible to our understanding of genetics and biological processes in all animals, including humans. Yet, despite being one of the most studied of animals, scientists are still finding the fruit ...
