For sexual reproduction to yield healthy offspring, newly generated oocytes—immature egg cells—must receive the correct amount of DNA after cell division. This process of segregating chromosomes ...
Researchers have revealed how bacteria precisely control the genes that trigger cell division. The study shows that the MraZ ...
A 'pocket' on the protein cyclin B is responsible for ensuring that the steps of cell division take place in the correct order. Cell division is key for life. Every organism -- from the smallest yeast ...
Among the many marvels of life is the cell's ability to divide and thus enable organisms to grow and renew themselves. For this, the cell must duplicate its DNA—its genome—and segregate it equally ...
Researchers created artificial kinetochore structures that reduce chromosome separation errors during meiosis in aging egg cells. By lowering microtubule pulling force, the approach helped maintain ...

Ichthyosporeans Sphaeroforma arctica and Chromosphaera perkinsii undergoing mitosis, depicted as two halves of a cell, rendered in Haeckel-inspired tones and a naturalist style. Cell division is one ...
A simple mechanism could underlie the growth and self-replication of protocells - putative ancestors of modern living cells - suggests a study publishing September 3 in Biophysical Journal. Protocells ...
