In all living organisms, the biomolecule transfer RNA (tRNA) plays a fundamental role in protein production. tRNAs are generated from precursor molecules in several steps. The enzyme tRNA splicing endonuclease (TSEN), among ...
Griffith-led research is revealing metabolic strategies that are surprisingly consistent across the rich diversity of life in the animal kingdom.
The inside of a living cell is crowded with large, complex molecules. New research on how these molecules could spontaneously organize themselves could further our understanding of how cells manage their essential biochemistry ...
N6-methyladenine (6mA) is as an important epigenetic modification in eukaryotes. Although 6mA was discovered at the same time as 5-methylcytosine (5mC), it has only recently received attention in eukaryotes, mainly due to ...
Scientists have known for decades that genes can be transferred from one species to another, both in animals and plants. However, the mechanism of how such an unlikely event occurs remained unknown. Now, researchers from ...
A team of researchers led by Feng Zhang at the Broad Institute of MIT and Harvard and the McGovern Institute for Brain Research at MIT has uncovered the first programmable RNA-guided system in eukaryotes—organisms that include ...
Scientists studying cells have long held the view that euchromatin, the part of chromatin that is made up of genes and is genetically active, is open and can be transcribed. A research team, looking at new evidence from genomics ...
Based on genetic blueprints, individual amino acids are assembled into long amino acid chains, the proteins, in the protein factories of our cells, the ribosomes. Each newly formed protein starts with the amino acid methionine. ...
Using cryo-electron tomography, researchers have uncovered details of how the dynein motor protein drives cilia to beat. Understanding this motion may help to tackle health problems that affect cilia, which range from fertility ...
TThor, the legendary Norse god from the mythological city of Asgard, is not alone. According to groundbreaking research published in the journal Nature, we humans—along with eagles, starfish, daisies and every complex organism ...
