Much the way the caps on the ends of a shoelace prevent it from fraying, telomeres - regions of repetitive DNA sequences and a protein structure - protect the tips of chromosomes from damage. Every ...

Inosine is a nucleoside that occurs naturally in transfer RNAs (tRNAs) and is essential for proper RNA translation. It is commonly found at the wobble position of anticodons, allowing for greater ...

A research team from the University of Cologne and collaborators has now shown that RNA interference, or RNAi for short, which is known to be a viral defense mechanism, also prevents the ...

Researchers at Arizona State University’s (ASU) School of Molecular Sciences and the Biodesign Institute’s Center for the Mechanism of Evolution have discovered an unprecedented pathway producing ...
