How is all of that DNA packaged so tightly into chromosomes and squeezed into a tiny nucleus? Histones are a family of small, positively charged proteins termed H1, H2A, H2B, H3, and H4 (Van Holde ...

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 exploring gene editing as a way to correct trisomy at the cellular level. Using CRISPR-Cas9, researchers ...

How did humans evolve brains capable of complex language, civilization, and more? Scientists at UC San Francisco recently ...

A study of artificial human and chimpanzee nerve cells revealed how faster-evolving DNA gives neurons the ability to build ...

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

So, it's very easy to see,” she said. To zoom in on changes in chromosome organization during meiosis, the researchers used nuclear membrane and DNA damage protein stains to track nuclear behavior.

Gene editing techniques may eventually allow trisomy to be treated at the cellular level, according to an in vitro ...

But some plants have taken a different approach. They have evolved sex chromosomes, the bits of DNA that make individual plants either male or female. In that club are organisms like the ginkgo ...
