Scientists from Oxford's Radcliffe Department of Medicine have achieved the most detailed view yet of how DNA folds and ...

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 ...

A study of newly created databases of medulloblastoma has found that patients with tumors containing circular extrachromosomal DNA - loops of DNA found outside of regular chromosomes - are twice as ...

Biology is no longer being hampered by the cell environment thanks to cell-free technology that makes it easier to clone DNA. Located in Tokyo, Japan, OriCiro Genomics is a pioneer in cell-free ...

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 diameter. By comparison, this corresponds to a 40-kilometer thread packed ...

In the early 1990s, scientists who were studying the development of a roundworm identified a small RNA molecule that regulated the expression of specific genes. This marked the discovery of microRNAs ...

Around 260 million people, more than three percent of the global population, are chronically infected with the hepatitis B virus (HBV); in the long term, this often leads to complications such as ...

Researchers have described a novel host strategy for combating viruses such as measles virus that affect the mitochondria, structures within the cell. The presence of the RNA genome of the measles ...

Mumbai: A team of researchers from the Indian Institute of Technology Bombay (IIT-B) has shed light on how a seemingly useless piece of DNA manages to outsmart yeast cells and ensure its survival ...
