Calico cats inspire X chromosome research
Calico cats, renowned and beloved for their funky orange and black patchwork or "tortoiseshell" fur, can thank X chromosome inactivation or "silencing" for their unique look.
Discovery upends model for how dividing cells monitor equal distribution of their chromosomes
Ludwig researchers Arshad Desai and Christopher Campbell, a post-doctoral fellow in his laboratory, were conducting an experiment to parse the molecular details of cell division about three years ago, when they engineered ...
Scientists discover that chromosomal rearrangements can be advantageous
In a pioneer study published in the latest issue of the scientific journal Nature Communications, a research team at the Instituto Gulbenkian de Ciência (IGC; Portugal), led by Miguel Godinho Ferreira in col ...
How chromosome ends influence cellular aging
By studying processes that occur at the ends of chromosomes, a team of Heidelberg researchers has unravelled an important mechanism towards a better understanding of cellular aging. The scientists focused on the length of ...
Researchers build a map of sites where genetic information is swapped between chromosomes
Was the dawn of man among trees in the cradle of disease?
A student-led conference to be webcast live will ask, in light of recent research, whether the story of human origin is radically different from established thinking, and what that might mean for everything ...
DNA found outside genes plays largely unknown, potentially vital roles
A new UC San Francisco study highlights the potential importance of the vast majority of human DNA that lies outside of genes within the cell.
Epigenetic regulation required to ensure correct number of chromosomes
Abnormal number of chromosomes is often associated with cancer development. In a new study published in the journal Nature Structural and Molecular Biology researchers at Karolinska Institutet in Sweden have shown that a ...
How fast you age depends on your parents
In the hunt for better knowledge on the aging process, researchers from Lund University have now enlisted the help of small birds. A new study investigates various factors which affect whether chicks are ...
DNA: How to unravel the tangle
A research coordinated by the scientists at SISSA of Trieste has now developed and studied a numeric model of the chromosome that supports the experimental data and provides a hypothesis on the bundle's function.
Head-on collisions between DNA-code reading machineries accelerate gene evolution
Bacteria appear to speed up their evolution by positioning specific genes along the route of expected traffic jams in DNA encoding. Certain genes are in prime collision paths for the moving molecular machineries ...
Unravelling the secrets of maleness
New research has identified the key to becoming male is an enzyme that "unravels" DNA to trigger male development of the embryo, a discovery that may give greater insight into intersex disorders.
Fungal sex can generate new drug resistant, virulent strains
Though some might disagree, most biologists think the purpose of sex is to create diversity among offspring. Such diversity underpins evolution, enabling organisms to acquire new combinations of traits to ...
Rewiring stem cells
A fast and comprehensive method for determining the function of genes could greatly improve our understanding of a wide range of diseases and conditions, such as heart disease, liver disease and cancer.
