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 half-century-old field of cytogenetics. Chromosome-level ...

Researchers found three master genes that alter brain development in Down syndrome, offering new clues about learning and memory differences.

Three specific genes on chromosome 21 drive widespread brain changes in Down syndrome, uncovering a new framework for ...

Conservation of genomic sequences between species indicates regions of functional importance, containing protein-coding gene, non-coding genes or regulatory elements. In the December 5 Nature, ...

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, ...
