New research predicts the location of DNA sequences that can form structures besides the canonical double helix — non-B DNA — in the recently released telomere-to-telomere genomes of the great apes, finding that non-B DNA is enriched in newly deciphered genomic regions, including telomeres and centromeres. Image shows evolutionary relationships among the great apes, left from top to bottom, including chimpanzee, bonobo, human, gorilla and two orangutan species and illustrations of representative chromosomes, right, with canonical helical and non-B DNA.
