Defect in transport system causes DNA chaos in red blood cells
Within all our cells lies two meters of DNA, highly ordered in a structure of less than 10 micro meters in diameter. Special proteins called histones act as small building bricks, organising our DNA in this structure. Preservation ...

Something old, something new: Evolution and the structural divergence of duplicate genes
(PhysOrg.com) -- Gene duplications are arguably the driving force of organismal evolution – and if they survive, such duplicate genes will diverge in both regulatory and coding genomic regions. Coding ...

Built-in 'self-destruct timer' causes ultimate death of messenger RNA in cells
Researchers at Albert Einstein College of Medicine of Yeshiva University have discovered the first known mechanism by which cells control the survival of messenger RNA (mRNA) -- arguably biology's most important molecule. ...

The art of stabilizing entangled spaghetti-like materials
Gene therapy can only be effective if delivered by a stable complex molecule. Now, scientists have determined the conditions that would stabilise complex molecular structures that are subject to inherent attractions and repulsions ...

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 ...

Enzymes for cell wall synthesis conserved across species barriers
Plants have neither supportive bone tissue nor muscles, and yet they can form rigid structures like stalks and even tree trunks. This is due to the fact that plant cells are enveloped by a stable cell wall. The main component ...
