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, ...

Humans and baker's yeast have more in common than meets the eye, including an important mechanism that helps ensure DNA is copied correctly, reports a pair of studies. The findings visualize for the ...

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 ...

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 ...

In Wikipedia, there are 21 scientists listed who made significant contributions to determining the structure of DNA. In recent decades the focus has been on the contributions of only 3 of those ...

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 ...

DNA's iconic double helix does more than "just" store genetic information. Under certain conditions it can temporarily fold into unusual shapes.
