Uncovering the unique roles of Exportin-5 in RNA export within Drosophila cells
Eukaryotic cells are complex biological units, each with multiple membrane-bound compartments. These cells use specialized mechanisms to export biomolecules from their synthesis site to where they function......»»
Glitch in protein synthesis could affect tumor growth
During protein synthesis, or translation, genetic information transcribed in the cell's mRNA directs the stringing together of amino acids—the building blocks of proteins. As the translation machinery carouses along the string of nucleotides that m.....»»
The Earth"s inner core is an enduring mystery: Here"s how researchers are starting to solve it
Deep beneath our feet, at a staggering depth of over 5,100km, lies Earth's inner core—a solid ball of iron and nickel that plays a crucial role in shaping the conditions we experience on the surface. In fact, without it we'd be unlikely to even exi.....»»
