These include some obvious mechanical activities such as endocytosis, cell motility and membrane resealing, but also others, such as replication and transcription. Taking the motor proteins as an ...

The outer membrane is permeable to small ... fluid-filled vesicles called vacuoles within their cytoplasm. Vacuoles typically compose about 30 percent of a cell's volume, but they can fill as ...

Animal and plant cells differ and they have similarities. Nucleus, cell membrane, cytoplasm and mitochondria are four cell components that are found in both animal and plant cells. All life on ...

For example, mycoplasmas do not have a cell wall. 12 These organisms rely on their cell membrane for structural integrity and often exhibit unique adaptations to survive without the rigidity of a cell ...

membraneless structures help compartmentalize the cytoplasm, as well as the interior of the nucleus. In contrast to organelles with a lipid bilayer membrane, membraneless structures are formed through ...

As a grad student in cell biology, Shaeri Mukherjee was always on the lookout for new ways to fiddle with cells’ internal structures. It was the early 2000s, and Mukherjee was working in Dennis ...

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation.

Communication between oocytes and granulosa cells is essential for oocyte formation, dormancy, reawakening, and maturation. Researchers have demonstrated that a protein complex called the exocyst ...
