Sex chromosomes—why the Y genes matter
Several genes have been lost from the Y chromosome in humans and other mammals, according to research published in the open access journal Genome Biology. The study shows that essential Y genes are rescue ...
Stress triggers key molecule to halt transcription of cell's genetic code
If DNA is the cookbook of life, then RNA is the scratch paper where the cell writes down its favorite recipes. These recipes could make the pigments of your skin, the vehicles that carry oxygen through your ...
Breakthrough helps explain how DNA is organized in our cells
A team of researchers at the IRCM led by François Robert, PhD, uncovered a critical role for two proteins in chromatin structure. Their breakthrough, recently published in the scientific journal Molecular Ce ...
From worker to queen at the drop of a gene
Biologists from the University of Leicester have discovered that one of nature's most important pollinators - the buff-tailed bumblebee – either ascends to the status of queen or remains a lowly worker ...
'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 ...
Beyond average: New platforms genetically barcode tens of thousands of cells at a time
Imagine someone hands you a smoothie and asks you to identify everything that went into it.
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 ...
Researchers use CRISPR to create 'kill switch' for GMOs
Geneticists clock genetic differences between 'larks' and 'owls'
A new study by geneticists from the University of Leicester has for the first time identified the genetic clues behind what makes you a 'lark' or an 'owl'.
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.
Tweaking the beak: Retracing the bird's beak to its dinosaur origins, in the laboratory
Scientists have successfully replicated the molecular processes that led from dinosaur snouts to the first bird beaks.
DNA with self-interest: Transposable element conquers new strain of fly
Transposable elements are DNA sequences that are capable of changing their genome position by cut and paste or copy and paste through the enzyme transposase. This ability can be harmful for hosts if transposable ...
Altering genes with the aid of light
Scientists have been manipulating genes for a while. The University of Pittsburgh's Alexander Deiters just found a way to control the process with higher precision.
Gene required for plant growth at warmer temperatures discovered
Researchers have discovered a new gene that enables plants to regulate their growth in different temperatures.
