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 ...

A new study led by NYU Langone Health researchers has found that cancer cells are better able to resist treatments when 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 ...

Imagine a chromosome. You’re probably picturing a nice little X shape, aren’t you? That’s probably what your high school science teacher taught you, anyway. Well, it turns out that’s not actually what ...

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, ...

A new study led by NYU Langone Health researchers found that cancer cells are better able to resist treatments when they have ...

Sex chromosomes must exchange genetic information at a short region during meiotic cell division. Molecular factors have now been found that alter sex-chromosome structure and enhance this exchange ...

An estimated 7% of all men are affected by infertility. Multiple animal studies indicate that exposure to persistent ...

In high school textbooks, human chromosomes are pictured as wonky Xs like two hotdogs jammed together. But those images are far from accurate. "For 90 percent of the time," said Jun-Han Su, ...

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 ...

A new study sheds light on how organisms have evolved to address imbalances in sex chromosomes. The study looks at a species of softshell turtle, but the results could help to illuminate an important ...
