A major milestone has been reached, with experts across Europe, including those at the Wellcome Sanger Institute in Cambridge, UK, sequencing 1,000 species of butterflies and moths. This includes almost all UK butterflies, ...
"Adapt or perish, now as ever, is nature's inexorable imperative," wrote H. G. Wells. This principle—that survival requires change—was mastered billions of years ago by single-celled organisms living in extreme heat. Over ...
Life's instructions are written in DNA, but it is the enzyme RNA polymerase II (Pol II) that reads the script, transcribing RNA in eukaryotic cells and eventually giving rise to proteins. Scientists know that Pol II must ...
In a study published in the journal Nucleic Acid Research, a research team at Karolinska Institutet has performed a large-scale genetic screen to uncover the hidden roles of tiny proteins, so-called microproteins.
A research team from the Faculty of Science, Charles University in Prague has discovered Solarion arienae, an extremely rare and morphologically unique unicellular eukaryote that sheds new light on early eukaryotic evolution.
Multicellular organisms (animals, plants, humans) all have the ability to methylate the cytosine base in their DNA. This process, a type of epigenetic modification, plays an important role in conditions such as cancer and ...
Cells are regularly faced with environmental stresses that may damage or destroy them. To survive, they quickly adjust their gene expression to protect themselves. This is especially true for cancer cells, which must contend ...
Janelia researchers have uncovered a novel way that two of the structures inside cells—the endoplasmic reticulum (ER) and lysosomes—coordinate the production of proteins, highlighting how interactions between organelles are ...
Genomes are key to unlocking life's evolutionary history. The presence and absence of certain genetic sequences and mutations can give us clues to the order in which species diverge. However, even state-of-the-art methods ...
Although heart cells and skin cells contain identical instructions for creating proteins encoded in their DNA, they're able to fill such disparate niches because molecular machinery can cut out and stitch together different ...
