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

Some chromosomes, such as B chromosomes, can increase their inheritance rate to their own advantage. These extra chromosomes are found in many plants, animals, and fungi and rely upon various ...

Trisomy is a genetic condition characterized by the presence of an extra chromosome. This means that the affected person has three copies of the 21st chromosome instead of two. The most common forms ...

Researchers using modern gene-editing tools have discovered that the intuition of scientists from more than a century ago was right: Cells with unusual numbers of chromosomes are drivers of cancer.

B chromosomes, often termed supernumerary chromosomes, represent non-essential additions to the standard (A) chromosome set in many eukaryotes. Despite being dispensable, they offer a unique window ...

A comprehensive genetic analysis of over 200,000 men has found that around one in 500 have an extra sex chromosome, with most of them unaware. That’s a much higher proportion than previously thought, ...

Most chromosomes have been around for millions of years. Now, researchers have revealed the dynamics of a new, very young chromosome in fruit flies that is similar to chromosomes that arise in humans ...

Cancer cells have special adaptation mechanisms that allow them to proliferate despite changes in their genetic makeup. Researchers at RPTU University Kaiserslautern-Landau, Southwest Germany, have ...

A new University of Utah-led study has discovered the mechanism behind a decades-old evolutionary mystery-how "selfish chromosomes" cheat the rules of genetic inheritance.
