Spliceosomal introns are noncoding DNA sequences located between exons in many eukaryotic protein-coding genes. Most are removed post-transcriptionally by RNA splicing and do not encode proteins, but they have been implicated ...
Viruses lack the molecular machinery required for protein synthesis. Instead, they hijack the host's protein-making machinery, specifically ribosomes and translational factors. This process is essential for viral multiplication ...
How do microorganisms orient themselves to find the optimal habitat? Scientists have thoroughly investigated so-called magnetotactic bacteria, which use the Earth's magnetic field as a biological compass. Some eukaryotic ...
How life started on our own planet may not seem as interesting as finding evidence of life on Mars or the icy moons Europa or Enceladus. But the search for the first eukaryotes on Earth remains as important to astrobiology ...
They are the cell's "gatekeepers": specialized proteins, known as transporters, selectively control which substances enter a cell and which do not. Researchers at the University of Münster and the National and Kapodistrian ...
Inside the cell nucleus, genes must be turned on and off with precision to regulate biological processes. The first models of gene regulation were developed in the 1960s, yet modern science continues to uncover new layers ...
Researchers from Heinrich Heine University Düsseldorf (HHU) have—in collaboration with colleagues from Ludwig Maximilian University (LMU) in Munich—analyzed the complex biochemical processes that bacteria use to insert proteins ...
Hopefully, we're about to travel back to the moon relatively soon. And while the original "giant leap for mankind" was taken by a human, Neil Armstrong brought a plethora of other forms of life along with him. Humans themselves ...
A decade ago this summer, at the Marine Biological Laboratory, Jocelyn Malamy watched jellyfish cells "walk" toward each other to close a wound for the first time. An associate professor of molecular genetics and cell biology ...
Biomaterials with extraordinary properties, such as spider silk, have so far been known primarily from animals. Researchers at the University of Salzburg in Austria have now deciphered a surprising counterpart from the world ...
