The awe-inspiring process of cell division can turn a fertilized egg into a baby – or a cancerous cell into a malignant tumor. With so much at stake, nature keeps it tightly controlled in a process ...

Working with human breast and lung cells, Johns Hopkins Medicine scientists say they have charted a molecular pathway that can lure cells down a hazardous path of duplicating their genome too many ...

Before cells can divide, they first need to replicate all of their chromosomes, so that each of the daughter cells can receive a full set of genetic material. Until now, scientists had believed that ...

Cell division is one of the most fundamental processes of life. From bacteria to blue whales, every living being on Earth relies on cell division for growth, reproduction, and species survival. Yet, ...

A zebrafish embryo during the first cell division cycle, with the structural protein actin labelled, which marks the cell boundary and ingressing furrow. The image shows a time course from dark orange ...

A simulated cell in the early stages of division. Left half shows membrane (green cubes), and ribosomes (yellow/purple) interwoven through in the cell’s chromosome (red). Right side shows all the ...

Biologists have uncovered a quality control timing mechanism tied to cell division. The 'stopwatch' function keeps track of mitosis and acts as a protective measure when the process takes too long, ...

Before a cell can divide, it has to precisely duplicate its entire genetic information. However, the DNA in the cell exists as part of a DNA-protein complex known as chromatin. For this purpose, the ...

(Nanowerk News) By simulating the life cycle of a minimal bacterial cell — from DNA replication to protein translation to metabolism and cell division — scientists have opened a new frontier of ...

Classic screens for genes that regulate the cell division cycle (CDC genes) in yeast have searched for temperature-sensitive mutants with a loss-of-function phenotype. In the March 27 Proceedings of ...
