Microtubules, the dynamic filaments that form the cell's internal scaffolding, have long been viewed as mere passive ...

A central question in molecular biology is how cells protect their chromosomes from damage during repeated cell division. At ...

Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate ...

Cancer cells with extra chromosomes depend on those chromosomes for tumor growth, a new study reveals, and eliminating them prevents the cells from forming tumors. The findings, said the researchers, ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed.

A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they divide, a key process in keeping cells healthy. Using yeast, the researchers ...

Scientists now believe the Y chromosome, found in males, plays a bigger role in health and aging than once thought. Earlier, ...
