Human cells have two copies of each chromosome, and this balance is essential for genes to be expressed in the appropriate proportions and for cells to function correctly. When errors occur during ...

Aging men often lose the Y chromosome in a growing number of their cells—and it may be far more dangerous than once believed. This loss has been linked to heart disease, cancer, Alzheimer’s, and ...

Human sex chromosomes originated from a pair of autosomes, the ordinary or non-sex chromosomes that contain the majority of our genome and come in identical pairs. That ancestral pair of autosomes ...

Scientists have discovered a new property of the molecular motors that shape our chromosomes. While six years ago they found that these so-called SMC motor proteins make long loops in our DNA, they ...

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 ...

There are only so many ways to cram DNA into a cell’s nucleus, a study suggests. A cell’s complete genetic blueprint, or genome, is densely packed into chromosomes, condensing meters of DNA into a ...

AMES, Iowa – A new study led by an Iowa State University scientist sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, ...
