Transfer RNAs (tRNAs) are ancient workhorse molecules and part of the cellular process that creates the proteins, critical building blocks of life that keep a cell running smoothly. A new discovery suggests that the number of human genomic loci that might be coding for tRNAs is nearly double what is currently known. Most of the newly identified loci resemble the sequences of mitochondrial tRNAs suggesting … Continue reading Researchers find human genomic loci coding for tRNAs is double what is currently known.
