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, ...

For decades, biology textbooks taught that DNA’s story could be told with a single image: two elegant strands twisting in a double helix. That picture is still right, but it is no longer enough.

(AP) - James D. Watson, whose co-discovery of the twisted-ladder structure of DNA in 1953 helped light the long fuse on a revolution in medicine, crimefighting, genealogy and ethics, has died. He was ...
