Ordinarily, DNA lesions are difficult or impossible to amplify, but with the new method, each lesion is replaced by an unnatural, and copy-able, base pair. Affix another chemical label, 18-crown-6 ...

The normal, hydrogen-bonded base pairs found in DNA. Credit: MIT The new paper, released by Nature today, uses the synthetic bases shown at top.

In 1953, scientists proposed that DNA is structured as a double helix, with the chemical bases—adenine (A), cytosine (C), guanine (G), and thymine (T)—stacked up in pairs between two ...

Centromeres, specialized regions located at the center of chromosomes, are critical for ensuring proper cell division. During mitosis, centromeres serve as assembly sites for complex protein ...

The synthetic DNA had none of the A-T pairs that occur in natural DNA. In Jerusalem, Porath’s team immobilized the strands on a metal surface kept under vacuum at about –200°C.

Researchers investigating expanding the DNA “alphabet”—developing artificial bases that can potentially encode more information than the standard A, T, C, and G—have found that DNA polymerase is more ...
