In almost every human cell, two metres-long DNA has to fit within a nucleus that is just 8 millionths of a metre wide. Like wool around a spool, the extreme space challenge requires DNA to wrap around ...

An article by UAB professor Joan-Ramon Daban analyzes in depth the physical problems associated with DNA packaging that have often been neglected in structural models of chromosomes. The study ...

Scientists are increasingly interested in the function of chromatin -- a mix of DNA and protein within chromosomes -- and its role in disease. Using mathematical modeling and optical imaging they ...

Researchers have discovered a cellular mechanism that helps nocturnal mammals see in the dark. Mice, cats, deer, lemurs, and other mammals that are active at night remodel the DNA within their eyes to ...

In biology you must have come across the two types of cells, the prokaryotic and eukaryotic cells. These two are the most ...

Researchers now reveal that nature's storage solution first evolved in ancient microbes living on Earth between one and two billion years ago. In almost every human cell, two metres-long DNA has to ...
