Gene Expression Austerity April 19, 2016 Dr Michael Aregger, Dr Victoria Cowling and colleagues have published a study which reveals how transcription and mRNA capping are co-ordinated during the burst of gene expression that occurs after new cells are formed. mRNA typically comprises less than 5% of cellular RNA; mRNA capping flags these transcripts for the processing and translation required to make proteins.
