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

Researchers from Northwestern University have stumbled upon a previously unobserved function of a protein found in the cell ...

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, ...

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 ...

HIV inserts its genes into the host cell's nucleus in an unusual way. It doesn't import its RNA genetic material piecemeal. Instead, it stuffs its whole wedge-shaped capsid—basically the whole ...

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

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

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

Each component of a cell has its own function. Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found ...
