'Measuring stick' standard for gene sequencing now available from NIST
The world's first reference material to help ensure laboratories accurately "map" DNA for genetic testing, medical diagnoses and future customized drug therapies is now available from the National Institute ...
Partly human yeast show a common ancestor's lasting legacy
Despite a billion years of evolution separating humans from the baker's yeast in their refrigerators, hundreds of genes from an ancestor that the two species have in common live on nearly unchanged in them ...
When extra X chromosome won't stay silent, rogue RNA may be to blame
Each baby girl starts out with two X chromosomes, but to be healthy she only needs the genes from one. The extra X chromosome gets trussed up and shut down in the earliest stages of development.
Genetic markers for fetal overgrowth syndrome discovered
Humans and cattle share a similar epigenetic fetal overgrowth disorder that occurs more commonly following assisted reproduction procedures. In humans, this disorder is called Beckwith-Wiedemann syndrome ...
Chromosome-folding theory shows promise
Human chromosomes are much bigger and more complex than proteins, but like proteins, they appear to fold and unfold in an orderly process as they carry out their functions in cells.
