P.1 right column bottom paragraph: "To address these questions, [investigators] set out to examine the coordination between transcription and mRNA degradation from an evolutionary perspective, by comparing two closely related yeast species, S. cerevisiae and S. paradoxus. These species diverged from a common ancestor ∼5–10 million years ago and maintained similar physiology and genomic sequences (∼90% identity), yet as [they] have shown previously [ref 25], most of their orthologous genes have diverged in mRNA levels." |
