Northwestern Medicine scientists have discovered new details about how the human genome produces instructions for creating ...

Dubal and Abdulai-Saiku were especially interested in whether the origin of the X chromosome – from mom or from dad – mattered to cells. They knew that when egg and sperm cells form, chemical tags are ...

Mitosis orchestrates eukaryotic cell division, maintaining genetic fidelity and playing a key role in development, tissue homeostasis, and cancer progression.

The team discovered multiple pathways for dsRNA to enter the worms' cells ... "jumping genes"—DNA sequences that tend to move or copy themselves to different locations on a chromosome.

Consider the fact that our cells all have the same DNA ... X-chromosome inactivation in female mammals, which is necessary so that females do not have twice the number of X-chromosome gene ...

New research has investigated the mechanism by which bivalency functions to poise genes for expression during cell differentiation, providing insight into a long-standing paradigm in the regulation of ...

This engineered genome will help experts tailor organisms to fit the needs of their ever-changing environments.

Neurons that secrete the neuropeptide orexin help mice decide between exercise and snacking.
