For the first time, scientists have witnessed the very moment DNA begins to unravel, revealing a necessary molecular event ...

Water shortens the shelf life of DNA. Biosample integrity is questionable for samples stored in a wet environment owing to the persistent risk of DNA hydrolysis, even at low temperature.

The applied physicist explains how the structure of 52,000-year-old genes hint at the biology of an extinct animal ...

On ATP hydrolysis, which releases the DNA, a new heteroduplex is produced if strand exchange has occurred. Otherwise, the filament reforms for additional ATPase cycles of dsDNA binding, homology ...

Some investigators find that very large DNA fragments transfer more efficiently after partial hydrolysis of the DNA by acid treatment. When acid treatments are used in the protocol, it is ...
