It's tricky to make an exact copy of yourself. Or at least it is for cells undergoing mitosis, where cells replicate ...

The humble Y chromosome may be the smallest chromosome in the mammalian genome (and getting even smaller), but it is mighty: ...

During prophase, the initial stage of mitosis, replicated chromosomes are compacted into thick fibres. The membrane that surrounds the nucleus subsequently breaks down and the chromosomes separate ...

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 ...

The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this pair contains two X chromosomes, while for most males, it contains one X chromosome and one Y ...

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, ...

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 ...

A human cell carries in its nucleus two meters of spiraling DNA, split up among the 46 slender, double-helical molecules that are its chromosomes. Most of the time, that DNA looks like a tangled ball ...

Researchers at Trinity have found that a largely overlooked form of cancer evolution, which drives aggressive disease and poor patient outcomes, is far more widespread than previously thought.

Get ready for a biology lesson. Certain plants have extra sets of chromosomes. And it turns out, it's a useful trait for a ...

Prenatal genetic tests can detect sex chromosome aberrations, but what happens after—for families and children—is anything but clear. When Ollie’s mother, Katie, was nine weeks pregnant, her ...
