Understand how maternal age influences pregnancy risks, chromosomal conditions, and why early screening and care can help ensure a healthy baby.

A metabolic enzyme also binds and unwinds RNA to promote translation of cell cycle genes. This dual role links energy status ...

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

On the flipside, if telomeres are too long, it can also spell trouble because cancer cells require long telomeres to become longer lived, ‘immortal,’” says Mia Levine, associate professor of biology ...

For many years, scientists have delved into human chromosomes and the DNA they carry, studying the genetic code in each cell ...

Biologists at the National University of Singapore (NUS) have uncovered how the protein NuSAP safeguards tiny structures inside cells called centrioles, revealing a mechanism linked to developmental ...

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 ...

Biologists at the National University of Singapore (NUS) have uncovered how the protein NuSAP safeguards tiny structures inside cells called ...

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 ...

A remarkably small bacterium containing fewer than 500 genes serves as the basis for one of the most detailed digital life ...

Scientists have uncovered how brewer’s yeast developed its unusually tiny centromeres, the DNA regions that guide chromosome ...
