Enzyme Key To ‘Sister Act’ That Maintains Genome Stability

Keeping the genome stable is a “sister act” of matched chromatids - the pairs of the double helix DNA molecule that exist during the chromosome duplication in the S phase of the cell cycle. Maintaining the chromatids in their sister pairs rests with Eco1, a kind of enzyme known as an acetyltransferase.
