A new study from Weill Cornell Medicine provides insights into how cells maintain the tiny end caps of chromosomes as they ...

Understanding the material basis of adaptive evolution has been a central goal in biology dating back to at least the time of ...

In evolutionary terms, fitness is defined as an organism's ability to survive and reproduce its genes into the next ...

While this internal rivalry is usually hard to see, it becomes clearer when it involves genes on the X and Y chromosomes ... Additionally, while spermatogenesis can occur without Slxl1/Slx ...

Chromosomes are the carrier of our genomic information and hold vital clues of the evaluation and therapeutic outcome of breast cancer. “In an innovative approach, our study explores how VPA ...

The planned changes include reinstating a version of chromosome testing that was discontinued in the 1990s, requiring athletes who compete in the female category to submit to a cheek swab or dry blood ...

each chromosome forms a compact X-shaped structure with two rod-like copies. How the cell achieves this feat remains largely unknown. Now, for the first time, EMBL scientists have directly ...

Before division, each chromosome transforms into a compact, X-shaped structure made of two identical, rod-like copies. But exactly how cells manage to reshape and organize their DNA for this process ...

The last few years have provided us with a new level of understanding of how chromosomes are replicated, segregated and read - and how their 3D organisation influences expression of individual genes ...

Females have one active X chromosome and one dormant X chromosome in each cell. But a study suggests that genes on the dormant X get "reawakened" later in life, potentially giving the brain a boost.
