Sunburns and aging skin are obvious effects of exposure to harmful UV rays, tobacco smoke and other carcinogens. But the ...

one can determine the sequence of the newly synthesized DNA strand from the 5′ to the 3′ end. One particularly striking finding of the Human Genome Project research is that the human ...

How does DNA recombination ... can then perform strand invasion, producing two Holliday junctions. From that point forward, resolution proceeds as in the single-stranded model (Figure 3).

In a study published in Nature, researchers report the successful in vitro reconstitution of meiotic DNA double-strand breaks (DSBs) formation. Meiosis, a specialized form of cell division in most ...
