In these cases, Down syndrome is caused by a translocation of chromosomes 15 and 21 (Figure 3), in which the long arms of two acrocentric chromosomes are translocated to produce a single long ...

have developed a new technique to measure the number of chromosomes in ancient genomes more precisely, using it to identify the first prehistoric person with mosaic Turner syndrome (characterized ...

Translocations generate novel chromosomes, but are often linked to disorders like infertility and cancer. How do these new chromosomes generate problems, and how are they detected? Translocations ...

The technique measures the amount of chromosomes in ancient human cells "more precisely", said researchers. They have also identified the first prehistoric person with mosaic Turner syndrome ...
