Soft tissue sarcomas (STS) are rare mesenchymal neoplasms that frequently show complex chromosomal aberrations such as amplifications or deletions of DNA sequences or even whole chromosomes. We ...

Kansas City, MO—September 24, 2025—Open a high school biology textbook, and you’ll see human chromosomes lined up two by two, like socks in a drawer. But in about one out of every 800 people, two ...

The Y chromosome is perhaps the most puzzling part of the human genome. Associated with male development, it is chock-full of repetitive and inverted stretches of DNA, a hurdle that makes it ...

During meiosis, the cell division process central to sexual reproduction, all chromosomes must figure out where to destroy the protein cohesin—the molecular glue holding chromosomes together—and where ...

For many years, the human Y chromosome was terra incognita. Scientists completed the genetic sequences of other chromosomes, the threadlike structures that hold an organism’s DNA. But more than 50 ...

* Evolutionary gene loss has steadily reduced the Y chromosome to a small set of essential genes * Gene// conversion may increase variation but does not restore lost genetic function * Future sex ...
