Researchers have identified two key proteins that act as genetic 'architects', creating the blueprint needed by embryos during the earliest stages of their development.
Ludwig Maximilian University researchers have monitored how epigenetic information is transmitted to daughter cells during cell division and determined when the cell's developmental memory is re-established.
Bacteria have traditionally been viewed as solitary organisms that "hang out on their own," says molecular biologist Kevin Griffith of the University of Massachusetts Amherst. However, scientists now realize that in fact, ...
Many proteins interact with an RNA molecule called Xist to coat and silence one X chromosome in every female cell. Learning how genes are targeted and silenced may help researchers studying sex-specific diseases.
When it comes to survival of the fittest, it's all about your mother - at least in the squirrel world.
Scientists on Monday said they have found a gene to help protect potatoes from a blight that unleashed a devastating famine in Ireland in the 19th century.
Honey bees use different sets of genes, regulated by two distinct mechanisms, to fight off viruses, bacteria and gut parasites, according to researchers at Penn State and the Georgia Institute of Technology.
Traditionally, to understand how a gene functions, a scientist would breed an organism that lacks that gene - "knocking it out" - then ask how the organism has changed. Are its senses affected? Its behavior? Can it even survive? ...
A scientific finding in fruit flies on the interplay of genes, nutrition and immunity provides insights that may one day inform personalized medicine.
Marc Bühler and his team at the Friedrich Miescher Institute for Biomedical Research (FMI) have elucidated the mechanism underlying small RNA-mediated gene silencing, thus solving a mystery which has been puzzling the research ...
