Plasmids, small circular DNA molecules found in bacteria, may contain antibiotic-resistance genes and have the ability to replicate independently. Bacteria can transfer these plasmids to one another, ...

An international collaborative research team has discovered that G-quadraplex DNA (G4-DNA) accumulates in neurons and dynamically controls the activation and repression of genes underlying long-term ...

Scientists have discovered that a protein once thought to simply help load a factor necessary for the copying of DNA, actually plays a key role in ensuring fast and reliable replication—an insight ...

The human genome has to be carefully organized so it will fit inside of the nuclei of cells, while also remaining accessible to the cellular machinery that works to express the right genes at the ...

When bacteria cells replicate, they do so a little differently than human cells do. They don’t undergo mitosis, a splitting that involves construction of spindles to carefully separate the DNA after ...

Estrogen is known as an important hormone, and it can control many cellular and bodily functions by regulating the activity of hundreds of genes. Scientists have now learned more about how estrogen ...

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 ...

In the middle of the 20th century, accumulating data suggested that DNA carries life’s genetic information. Biochemists around the world raced to determine its structure. The competition led to some ...
