Apart from carrying the information to encode proteins in, RNA molecules can adopt intricate 2D and 3D structures. Specifically, the same RNA molecule can switch between ON and OFF structures, ...

What made ribose the sugar of choice for life's code? Scientists at Scripps Research may have cracked a major part of this ...

In living organisms today, complex molecules like RNA and DNA are constructed with the help of enzymes. So how did these molecules form before life (and enzymes) existed? Why did some molecules end up ...

Analyses of zebrafish meioc mutants revealed that spermatogonial stem cells with low rRNA transcription caused by nucleolar Piwil1 require Meioc to keep Piwil1 in cytoplasm for the upregulation of ...

The nucleolus is where ribosomal RNA (rRNA) is transcribed, processed, and assembled into the building blocks of ribosomes, the molecular machines that make proteins. Researchers discovered that rRNA ...
