For decades, the Y chromosome — one of the two human sex chromosomes — has been notoriously challenging for the genomics community to sequence due to the complexity of its structure. Now, this elusive ...

For successful cell division, chromosomal DNA needs to be packed into compact rod-shaped structures. Defects in this process can lead to cell death or diseases like cancer. A new study has shown how ...

Researchers have made a surprising new discovery in the structure of the centromere, a structure that is involved in ensuring that chromosomes are segregated properly when a cell divides. Mistakes in ...

"Hearst Magazines and Yahoo may earn commission or revenue on some items through these links." The 23 rd chromosome base pair contains what are known as our sex chromosomes. For most females, this ...

Highly challenging to sequence and long overlooked, the human Y chromosome’s contributions to health and disease remain largely unknown. A new paper that presents, for the first time, the complete ...

New insights into the Y chromosome, including its role in disease, should flow from the complete DNA sequencing data now achieved by two international research teams. Although it is commonly reported ...

One of the challenges of working with ancient DNA samples is that damage accumulates over time, breaking up the structure of the double helix into ever smaller fragments. In the samples we've worked ...

The human genetic blueprint is deceptively simple. Our genes are tightly wound into 46 X-shaped structures called chromosomes. Crafted by evolution, they carry DNA and replicate when cells divide, ...

A major breakthrough in human genetics has been achieved with the complete decoding of the human Y chromosome, opening up new avenues for research into digestive diseases. This milestone, along with ...
