The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: ...

Researchers at the Francis Crick Institute studying male mice engineered with different Y chromosome deletions have uncovered which genes on the mouse Y chromosome regulate the development of sperm ...

Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...

New research tracks how cells prepare gene regulatory decisions that will define their fate during the earliest stages of ...

Scientists in Japan have developed a rat-mouse hybrid embryo from a single frozen rat chromosome transplanted into a mouse ...

The silencing of the one X chromosome in XX cells is mediated by XIST, a long noncoding RNA that is randomly transcribed from only one X early in development. It coats the DNA and shuts down gene ...
