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 ...
The E. coli genome is encoded on a contiguous ~4.6 Mb-long DNA molecule, compacted inside a micron-cubed cell. When reconstituted in vitro, chromosomes expand in a bulk that is challenging for probing ...
Cohesin is a key regulator of three-dimensional genome organization, contributing to gene regulation, recombination, DNA repair and chromosome segregation. Like other members of the evolutionary ...
Humans have 23 pairs of chromosomes, including a pair of sex chromosomes (typically XX for females, and XY for males). Chromosomes contain hundreds to thousands of genes, which are sections of DNA ...
Researchers at The University of Texas Medical Branch (UTMB) have identified how a key enzyme called ATR protects DNA from breaking when cells copy damaged genetic material, a discovery that could ...
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.

Is the Y chromosome disappearing? Scientists reveal the new gene that could define future men
In 2002, evolutionary biologist Jenny Graves revealed a provocative calculation in regard to the human Y chromosome, later mentioning that it "is running out of time." Over the past 300 million years, ...
How does your body produce millions of antibodies from one genome? New research reveals how two closely related proteins help ...
A base editor rewrote a single DNA letter while editing human embryos, and every chromosome held even as mosaicism keeps a ...
Small, cancer-associated DNA circles "hitchhike" on chromosomes during cell division to spread efficiently to daughter cells by co-opting a process used to maintain cellular identity through ...
Translocations are chromosomal “cut and paste” errors that drive many lymphomas, a type of blood cancer and the sixth most common form of cancer overall. This includes mantle cell lymphoma, a rare but ...
Findings published in the journal Nature show that 'SIRT7', a protein involved in how cells respond to stress and ageing, ...
