Microtubules tend to grow out from the centrosome to the plasma membrane. In nondividing cells, microtubule networks radiate out from the centrosome to provide the basic organization of the ...

Tantalizing clues in 4-billion-year-old asteroid Bennu samples could reveal particular molecular formations that some ...

Each day, a human adult loses on average 50 to 70 billion cells, which die from natural causes alone. New cells replace lost ...

Because the centrosomes are located outside the nucleus in animal cells, the microtubules of the developing spindle do not have access to the chromosomes until the nuclear membrane breaks apart.

Genetically, there are differences between bacteria and archaea, especially regarding their cell envelopes and metabolic processes. Microtubules are important for transport processes within a cell ...

The destabilizers resolve this issue by preferentially detaching the selfish centromere from tyrosinated microtubules and reorienting it toward the egg side. During oogenesis, only one of the haploid ...

"They appear to form the skeleton for the complex cell architecture of Asgard archaea," adds Florian Wollweber. In addition to actin filaments, eukaryotes also possess microtubules. These tube-shaped ...
