It has been known for several years that abnormal chromosome numbers lead to protein imbalances in the affected cells.

In fact, the Y chromosome is the most rapidly changing human chromosome, and even the most rapidly changing chromosome among great apes. This means two healthy people’s Y chromosomes can look very ...

The human genetic code will be built from scratch by British scientists in a controversial new research project. The £10 ...

The study leverages human data from the 1000 Genomes Project combined with mouse models of human X chromosome-linked DNA sequence variation to advance our fundamental understanding of development ...

Although women have two X chromosomes, each cell in a woman uses only one of their two X chromosomes. The other is switched off in a process called X-inactivation, so that the genes are not used.

While all human chromosomes contain repeats, more than 30 million letters of the Y chromosome — out of 62.5 million — are repetitive sequences, sometimes called satellite DNA or junk DNA.

This complete Y chromosome has 106 protein-coding genes, which is 41 more than in the reference genome. But almost all these extra genes are just copies of one gene called TSPY.. At the same time ...

The human Y did once contain as many genes as the X chromosome, but has lost them in the past 166 million years. As a result, most of the Y today is made up of repetitive "junk DNA ." ...

Complete X and Y chromosome sequences from six primate species reveal species diversity and insights into evolution. (Image credit: Ernesto Del Aguila III, National Human Genome Research Institute ...

In fact, the Y chromosome is the most rapidly changing human chromosome, and even the most rapidly changing chromosome among great apes. This means two healthy people’s Y chromosomes can look very ...
