Organelles in cells were originally often independent cells, which were incorporated by host cells and lost their ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments ...

Just as cities must carefully manage the flow of cars in and out of downtown, cells regulate the movement of molecules into ...

In addition to exporting materials out of the nucleus, the protein, called Exportin-1 (also called Xpo1 or Crm1), seems to play a role in promoting gene transcription, the process that creates RNA ...

A growing body of work suggests that cell metabolism — the chemical reactions that provide energy and building materials — ...

A new part of an ocean plant cell has been discovered that might revolutionize farming one day. The structure can take ...

Ten years ago, nobody knew that Asgard archaea even existed. In 2015, however, researchers examining deep-sea sediments discovered gene fragments that indicated a new and previously undiscovered form ...

One hypothesis is that the DNA loops could determine which genes are switched on in the cell. Inside a nucleus, chromosomes jumble together like a game of Twister. This can bring regulatory elements, ...

One of the key challenges of the modern genomics era is studying the thousands of genes in a single human cell at scale. To ...

Ultraviolet (UV) radiation is known to cause DNA damage, and while that damage may accumulate and eventually lead to diseases ...

During cell division, mitosis refers specifically to the separation of the duplicated genetic material carried in the nucleus. Mitosis is conventionally divided into five stages known as prophase ...

Glioblastoma stem cells with fluorescent labeling for prion protein (red), CD44 protein (green), and cell nucleus (blue) ...
