Each known chromosome 21 gene and predicted open reading frame (ORF), identified using MWG-Biotech's non-redundant proprietary database, is represented once in the array by a 40-nucleotide-long ...

Chromosome 21 Reveals Sparse Gene Content The unveiling of the DNA sequences of human chromosomes represents a new chapter in the unfolding story of genomics, but one with roots in the ...

How does the CRISPR Down Syndrome breakthrough work to remove the extra chromosome 21? We are closer than ever to a world where a genetic condition affecting one in every 700 babies could be ...

Scientists in Japan have used gene-editing technology to remove the extra chromosome responsible for Down syndrome, at least in lab-grown human cells. The project, led by Dr. Ryotaro Hashizume of ...

Also, in the second paragraph of the section headed ‘Comparison of chromosome 21 with other autosomes’, the second sequence should read ‘For example, a 100-kb region of a contig (AP001656 ...

After sifting through DNA from almost 10,000 people from ancient and pre-modern societies, we have discovered six cases of Down syndrome in past human populations.

Published online today in Science, a new study finds that telomere lengths follow a different pattern than has thus far been understood. Instead of telomere lengths falling under one general range of ...
