Evolution reveals missing link between DNA and protein shape

Fifty years after the pioneering discovery that a protein's three-dimensional structure is determined solely by the sequence of its amino acids, an international team of researchers has taken a major step toward fulfilling ...

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 ...

A better way to count molecules discovered

(PhysOrg.com) -- Researchers at the Swedish medical university Karolinska Institutet have developed a new method for counting molecules. Quantifying the amounts of different kinds of RNA and DNA molecules is a fundamental ...

New method for studying gene activity developed

(PhysOrg.com) -- Researchers from UQ's Institute for Molecular Bioscience (IMB), Harvard University and RocheNimblegen Inc. have developed a new method for examining genetic information that reveals clues to understanding ...

Process important to brain development studied in detail

Knowledge about the development of the nervous system is of the greatest importance for us to understand the function of the brain and brain disorders. Researchers at Uppsala University have examined the key step when genes ...

Researchers suspend, image single DNA molecules

(PhysOrg.com) -- Studying chemical modifications in the chromosomes of cells is akin to searching for changes in coiled spaghetti. Scientists at Cornell have figured out how to stretch out tangled strands of DNA from chromosomes, ...
