he explained. Keyser and his team have been investigating how plectonemes and other DNA structures form during natural processes, such as transcription. In earlier work, they explored how torsional ...

The DNA packed inside every human cell contains instructions for life, written in billions of letters of genetic code. Every time a cell divides, the complete code, divided among 46 chromosomes, must ...

In human cells, there are about 20,000 genes on a two-meter DNA strand—finely coiled up in a nucleus about 10 micrometers in ...

Researchers from the University of Birmingham have uncovered answers that provide the detail to explain two specific DNA repair processes that have long been in question. The publication of two papers ...

DNA is often called the blueprint of life, but what does that really mean? Elizabeth Worthey, Ph.D., associate professor, Department of Genetics in the Heersink School of Medicine, explains everything ...

Extrachromosomal DNAs (ecDNAs) are circular DNA structures located in the nuclei of cells outside chromosomes. They were originally discovered in chromosome spreads of cells obtained from embryonal ...

Chimpanzees, along with bonobos, are humans' closest living relatives. In fact, you may have heard that humans and chimps ...
