Pre-messenger RNA (pre-mRNA) splicing is an integral step in gene expression, removing introns that would otherwise disrupt the coding potential of gene transcripts. As published in the August 15th issue of G&D, Drs. Tommaso Villa and Christine Guthrie at UCSF have identified a novel splicing fidelity factor, as well as provide additional evidence for a two-step model of pre-mRNA splicing. The researchers found that deletion of the yeast gene ISY1 reduces the efficiency of the first step...

One of the key motivations for revisiting the probability of life elsewhere in the universe is the surprising proclivity of life in hostile places on Earth. New findings suggest that modern organisms may have useless DNA fragments today that once saved their ancestors lives in extreme environments. Astrobiology Magazine -- Yale scientists report in the journal Nature that the "missing" genes for tRNA in an ancient parasite are made up by splicing together sequences in distant parts of the DNA...
