More than 20 years ago, the human genome was first sequenced. While the first version was full of “holes” representing missing DNA sequences, the genome has been gradually improved in successive ...

The chromosome 22 sequence turned out to be a good preview of what the whole genome had in store. The spacing of repeated sequences along the chromosome and the presence of large-scale duplications ...

The chromosome associated with male development, which is the last mysterious piece of the human genome, has been fully sequenced by a team of more than 100 researchers around the world, including ...

Ideograms and partial karyotypes are shown. For the deletions, the arrows indicate a) the deletion of chromosome 15q11-13 associated with Prader-Willi and Angelman syndromes, and b) the deletion of ...

The male Y chromosome has disappeared from a species of rat, leading scientists to investigate how humans might also lose ours in the near future. It's not all bad news for men though, as a paper ...

Human biological sex is determined by the sex chromosomes X and Y. In most cases, females possess two X chromosomes, while males have one X and one Y. However, there is some evidence that the Y ...

One person in 2000 suffers from a microdeletion of chromosome 22 that can lead to the development of psychotic disorders, such as schizophrenia, in adolescence. In addition to symptoms such as ...

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.

For introducing regions of human chromosomes greater than a megabase into cells or animals, we have developed a chromosome-cloning system in which defined regions of human chromosomes can be cloned ...

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, ...
