Positively charged metal ions appear to act as tiny molecular bridges, helping negatively charged DNA helices overcome repulsion and align with remarkable precision.
A fascinating look at one of biology’s fundamental molecular interactions.

academic.oup.com Imaging and mechanism of DNA–DNA recognition mediated by divalent ions Abstract. In the cell, DNA must be tightly packed to facilitate its organization into the nucleus, where recognition of homologous sequences underpins key Scientists have discovered how DNA molecules overcome their natural electrical repulsion to pair together. Tiny metal ions act as molecular bridges, supporting a 20-year-old “DNA zipper” theory and offering new clues about cancer and biotechnology.View quoted post on X
