Cruciform Extrusion in Methylation-State Variants of pBR322 Plasmid [PDF]

open access: yes, 2007
The presence of DNA secondary structures in genomic DNA has been observed in both prokaryotes and eukaryotes. Specifically, sections of ssDNA may melt out and form cruciform/hairpin structures within palindromic sequences or areas of high purine content.

Absence of arsenate in DNA from arsenate-grown GFAJ-1 cells

open access: yes, 2012
A strain of Halomonas bacteria, GFAJ-1, has been reported to be able to use arsenate as a nutrient when phosphate is limiting, and to specifically incorporate arsenic into its DNA in place of phosphorus.
