Every time a cell divides, it must copy its DNA with extraordinary precision. But this process is constantly challenged by ...

When a gene is turned on in a cell, it creates a ripple effect along the DNA strand, changing the physical structure of the strand. A new study by MIT researchers, appearing in Science, shows that ...

The left-handed spiral of each Z-DNA strand is highlighted on the left. Binding and bonding of the two zinc finger domains (shown in red) from the CTCF protein to Z-DNA (shown in blue). This protein ...

Cells use a surprising “pearling” motion to evenly distribute mitochondrial DNA. This newly uncovered process may be key to ...

Researchers have found that the way DNA is packaged in cells can directly impact how fast DNA itself is copied during cell division. They discovered that DNA packaging sends signals through an unusual ...

The first crystal structure of an alternative DNA shape from the insulin gene has been revealed. The first crystal structure of an alternative DNA shape from the insulin gene has been revealed by a ...

Researchers have discovered that DNA wrapped around nucleosomes exists in multiple partially open states rather than simply locked or accessible configurations.

Every cell in the human body squeezes over six feet of DNA into a miniscule speck invisible to the naked eye—like compressing a whole house into a single sugar cube. In order to fit in a cell and ...

Researchers at The University of Texas MD Anderson Cancer Center have developed a new imaging method, known as RF-SIRF, that ...

There are photosynthetic bacteria known as cyanobacteria, and these microbes helped generate the oxygen that paved the way ...
