Stowers Institute researchers identified the precise fusion point of a chromosome variant that may contribute to infertility and recurrent pregnancy loss in some patients.

In human cells, DNA carries chemical or "epigenetic" marks that decide how genes will be used in different tissues. Yet in a ...

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

Merotelic kinetochore (single kinetochore attaches to microtubules from two spindle poles) has been proposed to be the major mechanism underlying the spontaneous formation of lagging chromosomes, ...

Centromeres play virtually the same central role across the entire tree of life: They ensure the faithful segregation of ...

The five phases of mitosis and cell division tightly coordinate the movements of hundreds of proteins. How did early biologists unravel this complex dance of chromosomes? The most obvious difference ...

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 ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

For palaeontologists, DNA is infuriatingly fragile. Its long chains begin to break apart shortly after death, destroying valuable information about the deceased parent organism. Unlike bones, ...

Humans contain 46 chromosomes (23 from their mother, and 23 from their father) in each of their body cells. This image shows duplicated chromosomes from a human male. Summary Scientists at the Sloan ...
