Painstaking new analysis of the genetic sequence of the X chromosome—long perceived as the "female" counterpart to the male-associated Y chromosome—reveals that large portions of the X have evolved to play a specialized ...

Many proteins interact with an RNA molecule called Xist to coat and silence one X chromosome in every female cell. Learning how genes are targeted and silenced may help researchers studying sex-specific diseases.

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

Though some might disagree, most biologists think the purpose of sex is to create diversity among offspring. Such diversity underpins evolution, enabling organisms to acquire new combinations of traits to adapt to their environment.

In humans and other animals, sex is usually determined by a single gene. However, there are claims that in some species, such as platyfish, it takes a whole "parliament" of genes acting together to determine whether offspring ...

In one of the mysteries of mammalian development, every cell in the early female embryo shuts down one of its two copies of the X chromosome, leaving just one functional. For years, the mechanics behind this X chromosome ...
