Human DNA, which is approximately two meters in length, is organized into a compact, thread-like structure known as the chromatin, so it could fit into the nucleus, a tiny sphere that’s only about six ...

Genes are segments of DNA (deoxyribonucleic acid) that are located inside every human cell. The DNA inside each cell is tightly coiled in structures called chromosomes. Each chromosome contains a ...

One of the most detailed 3D maps of how the human chromosomes are organized and folded within a cell's nucleus is published in Nature. Chromosomes are thread-like structures that carry a cell's ...

Transposons, or "jumping genes"—DNA segments that can move from one part of the genome to another—are key to bacterial evolution and the development of antibiotic resistance. Cornell University ...

DNA methylation is a key epigenome component that helps dictate how genes are expressed, contributing to normal cell and tissue differentiation during development, as well as the process of biological ...

Researchers sequenced the genomes of three medakas, or Japanese rice fish, which are a common model organism used for ...

Jumping genes and X chromosome disease risk: a new Science study finds that X-chromosome inactivation makes the silenced X ...

In a study published in the journal Science, researchers in Queensland and the United States discovered that the human X ...

Large and rare duplications and deletions in a chromosome region known as 22q11.2 , which involves genes that regulate cardiac development, are linked to nonsyndromic bicuspid aortic valve disease.

Scientists in Japan have used gene-editing technology to remove the extra chromosome responsible for Down syndrome, at least in lab-grown human cells. Down syndrome occurs when a person is born with ...
