Men tend to lose the Y chromosome from their cells as they age. But because the Y bears few genes other than for male ...

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

Most mammals, including humans, have two sex chromosomes, X and Y. One sex chromosome is usually inherited from each parent, and they pair up as either XX or XY in every cell of the body. People with ...

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 ...

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 ...

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 ...

Around the world, women outlive men. This is true in sickness and in health, in war and in peace, even during severe epidemics and famine. In most animal species, females live longer than males. Dena ...

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 ...

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 ...
