Proteins enable essential enzyme to maintain its grip on DNA

Scientists have identified a family of proteins that close a critical gap in an enzyme that is essential to all life, allowing the enzyme to maintain its grip on DNA and start the activation of genes. The enzyme, called RNA polymerase, is responsible for setting gene expression in motion in all cells. RNA polymerase wraps itself around the double helix of DNA, using one strand to match nucleotides and make a copy of genetic material.
