Novel mechanism for control of gene expression revealed

Scientists have recently discovered a novel, evolutionarily conserved mechanism for the regulation of gene expression. Normal cell growth, embryonic development, and responses to stress, require proper spatial and temporal control of gene expression. Studies on control of transcription (RNA biosynthesis) are typically centered on understanding how the RNA polymerase is recruited to the promoter, the control region of a gene. However, new work has revealed the existence of a second level of control in a yeast model system.
