Studies show aging men often lose the Y chromosome in some cells, a change now linked to heart disease, cancer, and shorter lifespans.

In a milestone achievement, a whole chromosome has been created from scratch by scientists for the first time ever. The tRNA Neochromosome is a man-made chromosome of the common baker's yeast ...

Researchers at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have identified a mechanism that protects the female ...

Yale scientists have discovered a new potential treatment avenue to fight cancer. Using CRISPR gene-editing, the team eliminated extra chromosomes from cancer cells and found that they could no longer ...

Chromosomes are thread-like structures located inside the nucleus of animal and plant cells. Each chromosome is made of protein and a single molecule of deoxyribonucleic acid (DNA). Passed from ...

X chromosome reactivation contributes to reducing the signs of disease in the female brain. Female cells have two X ...

In most mammals, females have two X chromosomes and males have one X and one Y chromosome in each of their cells. To avoid a double dose of X-linked genes in females, one of the Xs is silenced early ...

Triploidy is a condition that affects 1% to 3% of pregnancies. It’s when a developing baby has an extra set of chromosomes, the thread-like structures that carry DNA. A triploidy pregnancy usually ...
