The study of these phases, the proteins that regulate them, and the complex biochemical interactions that stop or start DNA replication and cell division ... biology of all organisms, from ...

As a result, all eukaryotes — from single-celled yeast to complex ... cell cycle and its checkpoint controls allows scientists to use relatively simple model organisms to learn more about cell ...

The division of all living organisms into the three domains of ... "They appear to form the skeleton for the complex cell architecture of Asgard archaea," adds Florian Wollweber.

The answer could lie in a special group of single-celled organisms with a cytoskeleton similar to that of complex ... within a cell and the segregation of chromosomes during cell division The ...

The structure is a new type of protein complex that the cell uses to attach to its surroundings and proves to play a key part in cell division. A new structure in human cells has been discovered ...

Cell division occurs when one cell divides to produce two new cells. Unicellular organisms use cell division to reproduce. Multicellular organisms use cell division for growth and repair of damage ...

“The first time we think it happened, it gave rise to all complex life.” Endosymbiosis where the host life form becomes fundamental to another organism’s function has only happened three ...

But at the most fundamental level, scientists are still struggling to grasp the physics behind how our own cells build, move, transport and divide. “The mechanisms that allow organisms to move ... the ...

High-resolution imaging of fruit flies at the University of Oregon has captured mechanical motions that stem cells use to make neurons, the cells that make up the brain. These motions coordinate ...

Their study sheds light on one of the most important questions in biology: how did ancient ancestors of simple cells like bacteria evolve to give rise to more complex organisms such as us humans?
