Cell powerhouses shape risk of heart disease

(Phys.org) —Genes in mitochondria, the "powerhouses" that turn sugar into energy in human cells, shape each person's risk for heart disease and diabetes, according to a study published recently by researchers at the University ...

Cell nuclei harbor factories that transcribe genes

Our genetic heritage is contained—and protected—in the nucleus of the cells that compose us. Copies of the DNA exit the nucleus to be read and translated into proteins in the cell cytoplasm. The transit between the nucleus ...

Plants let chloroplasts know the time

(Phys.org) —Plant cells communicate information about the time of day to their chloroplasts, the part of their cells that underpins all agricultural productivity on Earth, researchers at the University of Bristol have demonstrated ...

When the cell's two genomes collide

(Phys.org)—Plant and animal cells contain two genomes: one in the nucleus and one in the mitochondria. When mutations occur in each, they can become incompatible, leading to disease. To increase understanding of such ...

Chromosome 'anchors' organize DNA during cell division

For humans to grow and to replace and heal damaged tissues, the body's cells must continually reproduce, a process known as "cell division," by which one cell becomes two, two become four, and so on. A key question of biomedical ...

On the move for repair

Scientists from the Friedrich Miescher Institute for Biomedical Research have elucidated mechanisms that control DNA movement in the nucleus. They found that DNA with double-strand breaks moves more than undamaged DNA, thereby ...

Genes may travel from plant to plant to fuel evolution: study

The evolution of plants and animals generally has been thought to occur through the passing of genes from parent to offspring and genetic modifications that happen along the way. But evolutionary biologists from Brown University ...
