In prokaryotes, the circular chromosome is contained in the cytoplasm in an area called the nucleoid. In contrast, in eukaryotes, all of the cell's chromosomes are stored inside a structure called ...

Plastic chemicals may harm DNA, as new research reveals how additives disrupt nematode egg formation, suggesting risks to human reproductive health.

Scientists from Delft, Vienna, and Lausanne discovered that the protein machines that shape our DNA can switch direction.

Each human body cell contains 46 chromosomes. These can be arranged into 23 pairs. Each chromosome in a pair carries the same types of genes. The 23rd pair are the sex chromosomes: In females ...

Chromosomes are tightly coiled structures in each of your cells that contain DNA, the code for all life. DNA is organized in segments on chromosomes called genes. Humans typically have 46 ...

Bits of DNA from mitochondria can skip surprisingly fast into our genome and may reduce lifespan M ost of us remember two ...

In a study that could help scientists better understand and manipulate cell division, RIKEN biologists have engineered ...

The centromere of chromosomes plays a crucial role in cell division. Using the model plant Arabidopsis thaliana, an ...

In many organisms, aging is a clear risk factor for increased rates of chromosome mis-segregation, the main source of aneuploidy. Here, we report that old yeast mother c ...

Loss of the Y chromosome (LOY) in men, a dynamic mutation linked to aging, impairs immune function and increases risks of ...

Scientists found that healthy women can carry genetic changes in their breast cells that are thought to be characteristic of ...
