Scientists in Japan have developed a rat-mouse hybrid embryo from a single frozen rat chromosome transplanted into a mouse ...

Scientists discovered a new gene family on the Y chromosome of deer mice, challenging the belief that the chromosome only ...

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

In each cell of your body, DNA is stored in structures called chromosomes. When cells divide, these chromosomes are copied, ...

In humans and many other animal species, sex is determined by specific chromosomes. How did researchers discover these so-called sex chromosomes? The path from the initial discovery of sex chromosomes ...

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 ...

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, ...

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 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 ...

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 ...

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, ...
